Hi, You need to work out how many moles of water you have in 1L of water. Then you need to know that the Avrogadro constant is the number of molecules on a mole of anything. so; water = H2O Atomic weights: Hydrogen = 1 Oxygen = 16 Mole weight of water therfore; 18 grams 1L water = 1000 grams avrogadros constant is 6.0221415 x 10^23 :. 1000 /18 = 55.5555' moles water 55.5555' x Avrogadros const = 33456308210325000000000000 = 3.3456 x10 ^25 molecules of water. Please check my figures - I don't have a scientific calculator handy. Hope this helps, Mike.
1 liter of water has mass about 1000 grams/liter.
Molecular mass of water=18
so No. of moles in 1liter = 1000/18= 55.55 moles
this multiplied by Avogadro's number: 6.022*1023
will give number of water molecules in 1 liter as:
55.55*6.022*1023 ~= 334.52*1023
^^^
that's Avogadro's constant Written better as 6.022 X 1023
But that's not how many molecules of water there are in 1 mole of water, That would be the total amount of atoms there are in a mole though.
H2O
There are 2 Hydrogen atoms for every Oxygen atom.
Take that number above and divide it by 3
So there for there are 2.007 X 1023 Molecules of water in 1 mole of water.
See the Related Questions for a similar calculation and change the math accordingly.
[998.2 gram / 18.0 g/mole] x 6.022 x 1023 = 334 molecules/Litre at 20oC
1 L = 1 kg = 1000 g = 1000/18.0(g/mol) = 55.6 mol = 55.6(mol)*[6.0*10+23(molecules/mol)] =
= 33.3*10+24 molecules per litre water
(103 grams H2O)(1 mole/18 grams)(6.022X1023 molecules/mole) = 3.3346x1025molecules
In 1 mole of water there are 6.02x10^23 molecules (Avogadro's number)
how many water molecules there are in 1 kg of water
The mass of 49 mL of water is 49 g.
Of course, 6,022.10e23 molecules.
The number of water molecules is 16,728.10e23.
A mole of water contains avagadro's number of molecules of water. Therefore 5.65 moles contains 5.65 * 6.022x1023 molecules of water which equals 3.40243x1024 molecules of water.
water molecules in a can of soda = (wt/M.wt) x 6.023x1023
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
1kg of pure water would take up 1000 mililitres.
well the density of water at 25 oC is approximately 1kg/L. So about 1 L
The answer is 0,166.10e23 molecules.
How much salt is in 1kg of water
Of course, 6,022.10e23 molecules.
how many candles of 1kg wax
The latent heat of fusion of 1kg water is 334 kJ/kg. (Wikipedia)
It is: 5kg-1kg = 4kg
1kg=9.81N
The number of water molecules is 16,728.10e23.
A mole of water contains avagadro's number of molecules of water. Therefore 5.65 moles contains 5.65 * 6.022x1023 molecules of water which equals 3.40243x1024 molecules of water.
