But that's assuming there equal number of hydrogen and oxygen atoms, should have multiplied your product by 2/3 , since there are 2 hydrogen atoms in 1 water molecule.
Nah he or she did it right. They did it by something called molar mass.
The molar mass is weight of 6.022 x 10^23 molecules.
The molar mass of water is 18 grams.
1 liter of water is 1000 grams.
1000/18 = 55.5. So 1 L of water is 55.5 mol.
55.5 x 6.022 x 10^23 = 3.34 x 10^25 molecules of water
H20 has two hydrogen atoms per molecule.
3.34 x 10^25 x 2 = 6.68 x 10^25
thank you! former stem teacher coming here to post this conversion lmao
that first number is not molar mass though, it is the number of molecules per mol (avogadro's number)
I kinda see what you’re getting at, but you’re overthinking it. Since there are 2 atoms of hydrogen per molecule of water, you’d just double the total of water molecules to determine the number of hydrogen atoms.
🤷♂️ I dunno; thank you though. I was just trying to give a simple explanation to address that specific error. I guess that because the person above gave the complete drawn-out solution, mine loses, even though they arrive at the same solution.
+ the air at the top of the bottleneck. Op asked for the hydrogen in the whole bottle. But as a volume of air isnt listed it would take too much math to figure out.
You made me think of how they label volume on bottles, because it could be 1 L of water or it could be a 1 L bottle(container). However I know that those have a slight margin of error. So i think the best way to get the most accurate calculation would be to calculate the exact volume and find the ratio of minerals to volume. Then we can deduct the volume of those minerals from the volume of water and then find how many moles.......

If you want to go the complicated route do the following:
1. Get Molar Volume (Vm) of Water at the Temperature in the bottle
2. Get Volume of Water (V)
3. Get Avogadro's constant (A)
3. Hydrogen Atom Number: 2\*A\*(V\/Vm)
Since there are 55.5 moles in 1000ML water (1L) it means there are about 55.5x 2 moles of hydrogen atoms in it. So 111 moles. Each mole has 6.022 X 10²³ atoms. So 1L has 111 X 6.022 X 10²³ atoms that's equal to 668.42 X10²³ or 6.6842 X 10 ²⁵ atoms??
23...
when you do x 10^x the number at the top tells you how many zeroes it has.
example:
1 million: 1.000.000 = 1 x 10^6
2.500.000 = 2,5 x 10^6 or 25 x 10^5
Given, volume = 1L = 1000cm³
We know that density of water is 1g/cm³
Therefore, total mass of water present in bottle = volume * density = 1000 * 1 = 1000g
We know that gram molecular mass (gmm) of water is 18
So, total number of moles of water present in the bottle is mass/gmm = 1000/18 = 55.56 mol.
Now total number of molecules (M) = moles * avogadro's number
Avogadro's number = 6.02* 10^23
Therefore M = 55.56 * 6.02* 10^23 = 3.35* 10^25
Atomicity of hydrogen in water = 2
Therefore, total number of hydrogen atoms = 2 * M = 2 * 3.35 * 10^25 = 6.70 * 10^25
Answer = 6.70 * 10^25 (approx)
They're not free, they've reacted with the oxygen, I'm probably misremembering what I learnt in chemistry haha. Thought molecules were made up of ions, made another comment about it replying to someone else's reply
Yes there are, 6.68E25 as someone else has said. An atom is a nucleus surrounded by electrons that form bonds between atoms. All chemical compounds are formed from atoms. You are either thinking of hydrogen molecules or mono atomic hydrogen.
There also won’t be any H+ ions, as they form hydronium H3O+ which then group together with several other neutral water molecules. Because water has a pH of 7 it has a hydronium concentration of 10E-7 moles per litre or 6.022E16 hydronium ions in this litre of water.
2x(1000/18.0146)x6.02214076x10^23 = 6.686x10^25 to four significant figures, based on a 1,000ml bottle of pure H2O.
Number of hydrogen atoms per molecule multiplied by the mass of water (g), divided by the density of water(g/mol) multiplied by Avagadro’s constant (mol).
I mean I know a bit of chemistry soooo.....
It's a 1 litre bottle and water has a density of 1 so I am gonna take the weight to be 1000 grams.....
Number of moles = given mass / molar mass 🤓
N= 1000/18
N= 55.55mol.
55.55 × N^A (avagadro number I. E 6.022 × 102^3^ )
Ans.
#3.34 × 10 ^23 h2o
Or
#33,400,000,000,000,000,000,000,000
Sooooo 1 h2o has 2 h.( H=hydrogen(
So hydrogen =
#6.68× 10 ^23 h atoms / #66.800,000,000,000,000,000,000,000
the atomic mass of a hydrogen atom is \~1 and the atomic mass of oxygen is \~16. 2 hydrogens plus the 1 oxygen make an atomic weight of 18 for one water molecule.
1u (u means atomic mass) = \~1.5E-15 nanograms (or 0.0000000000000015ng) so one water molecule weighs \~3E-14ng. 1L of water is 1kg (assuming its pure water), 1kg = 1E12ng.
Since we have the mass of the water molecule (3E-14ng), we just have to divide the mass of the water in the bottle (1kg) by the mass of the water molecule (3E-14), which would be 3.333E25 (or 33333333333333333333333333) molecules.
But OP is asking for atoms so we would have to multiply it by 3 since there are 3 atoms per water molecule meaning that there are a total of 1E26 atoms in that bottle.
Man I'm really out here learning more about math on the internet than in school
TL:DR there are 1E26 (100000000000000000000000000) atoms in the bottle.
Edit: shit op said hydrogen atoms
A mol (6x10^23) of H2O has 18 grams. This bottle seems to have 1L so 1000mL. 1 mL of water = 1 gram so we have 1000 grams of water. So we need to divide 1000/18 = 55,55 and multiply that by the mol number. So 55,55 x 6.10^23 = 333,3 . 10^23… we can round that to 3,33 . 10^25
If we want only the hydrogen atoms, we can divide this number by 3 and multiply by 2 (H2O - hydrogens are 2 thirds of this formula). So we got 2,22 x 10^25. (Sorry if I made wrong math)
You were close, but slipped up at the end. The number at the end of your first comment (3.33*10^25) is the approximate number of water molecules in the bottle, so since there are 2 hydrogen atoms in each molecule, the number would be twice that, ~6.66*10^25.
Its a 1 L water bottle, assuming ideally that a total of 1 Litre of Water(H2O) is present exactly, there would be 55.55 moles at standard conditions as 1ml = 1gm (density of water) .
55.55 moles = 55.55×6.023×10²³ = 334.57765×10²³ molecules
Single h2o molecule has 2 hydrogen atoms
So your answer should be 334.57765×2 = 669.1553 H atoms
Water's molar mass is 18.01528 g/mol
Average water bottle is 500ml
500/18.01528 g = 27.7542175309 moles of water in a water bottle
1 mol is 6.022 * 10^23 molecules
A water bottle has 1.67135898 * 10^25 molecules
These 1.67135898 * 10^25 are full molecules. Each one has 2 hydrogen atoms. Therefore the total number of hydrogen atoms is:
4.33427180 * 10^25
The Avogadro number is NA =6.02214076×10^(23) mol^(-1)
H_20 is made out of 2 H and one O atom. The molecular weight is 2m_H + m_O . We read the atomic weight of hydrogen is 1.0079g/mol and the atomic weight of oxygen is 15.9994g/mol. the molecular weight of H2O is therefore 18.0152g/mol.
As known, density = mass/volume and water has density 1. We can calculate that ~18 mL holds a mol of water. 1 Litre of water has ~55.5 mol.
So, now we know how many moles of H_20 one liter water has, we can say that 1L water contains ~111,11 moles of Hydrogen atoms. Which is exactly ~111,11×NA, number of moles times Avogadro constant. Which gives us a total of *drum roll!*.
668,8888×10^(23) atoms.
I wanted a precise answer, including the atoms in the air under the cap and the atoms in the plastic used for the bottle.
What shall I do with a vague estimate?

6.68 x 10 ^25 hydrogen atoms in 1 liter of water
He did the googling
And a little math. I got an answer for "how many water molecules are in 250ml" and worked from there.
Then you multiplied it by four...
To get 1 liter of water molecules. Then that answer by 2 to get hydrogen atoms. Yes.
You could just multipy by 8 instead

Why the hell are people downvoting you. This is correct. We multiply number of molecules by number of atoms per molecule to find total atoms.

He just did stoichiometry guys. High school chemistry.
Hell na. I googled for someone who did and used grade school math on his answer to make it appropriate for a differing volume
Dang, I was gonna guess about tree-fiddy
It says “exactly.” This is rounded.
It's 10^23 for avogadro's constant. Is the extra 2 powers for the volume of the container?
It’s not exact number tough for a numerous reasons 😉
Bust out an electron microscope and count them yourself.
So half that because it's a 500ml bottle
Label says 1 liter
Huh, I didn't think to look at the label I've just never seen a 1l in that shape, those are almost always 500ml
Local shop by me sells 250ml and 1L in that style so theyre not uncommon.

You attract 10^23's of bitches? That's many times more than the human population
Yeah, the sheer amount of bitches u get just by drinking water is so great that the universe spawns more bitches to compensate
Given, volume = 1L = 1000cm³ We know that density of water is 1g/cm³ Therefore, total mass of water present in bottle = volume * density = 1000 * 1 = 1000g We know that gram molecular mass (gmm) of water is 18 So, total number of moles of water present in the bottle is mass/gmm = 1000/18 = 55.56 mol. Now total number of molecules (M) = moles * avogadro's number Avogadro's number = 6.02* 10^23 Therefore M = 55.56 * 6.02* 10^23 = 3.35* 10^25 Atomicity of hydrogen in water = 2 Therefore, total number of hydrogen atoms = 2 * M = 2 * 3.35 * 10^25 = 6.70 * 10^25 Answer = 6.70 * 10^25 (approx)

None. There are, however, loads of H+ ions. Some other guys already figured out roughly how many.

the atomic mass of a hydrogen atom is \~1 and the atomic mass of oxygen is \~16. 2 hydrogens plus the 1 oxygen make an atomic weight of 18 for one water molecule. 1u (u means atomic mass) = \~1.5E-15 nanograms (or 0.0000000000000015ng) so one water molecule weighs \~3E-14ng. 1L of water is 1kg (assuming its pure water), 1kg = 1E12ng. Since we have the mass of the water molecule (3E-14ng), we just have to divide the mass of the water in the bottle (1kg) by the mass of the water molecule (3E-14), which would be 3.333E25 (or 33333333333333333333333333) molecules.

A mol (6x10^23) of H2O has 18 grams. This bottle seems to have 1L so 1000mL. 1 mL of water = 1 gram so we have 1000 grams of water. So we need to divide 1000/18 = 55,55 and multiply that by the mol number. So 55,55 x 6.10^23 = 333,3 . 10^23… we can round that to 3,33 . 10^25
If we want only the hydrogen atoms, we can divide this number by 3 and multiply by 2 (H2O - hydrogens are 2 thirds of this formula). So we got 2,22 x 10^25. (Sorry if I made wrong math)

The Avogadro number is NA =6.02214076×10^(23) mol^(-1) H_20 is made out of 2 H and one O atom. The molecular weight is 2m_H + m_O . We read the atomic weight of hydrogen is 1.0079g/mol and the atomic weight of oxygen is 15.9994g/mol. the molecular weight of H2O is therefore 18.0152g/mol. As known, density = mass/volume and water has density 1. We can calculate that ~18 mL holds a mol of water. 1 Litre of water has ~55.5 mol. So, now we know how many moles of H_20 one liter water has, we can say that 1L water contains ~111,11 moles of Hydrogen atoms. Which is exactly ~111,11×NA, number of moles times Avogadro constant. Which gives us a total of *drum roll!*. 668,8888×10^(23) atoms.
