Assume 1 liter = 1 kilogram of water = 1000 grams of water.
Part A)
MW of hydrogen is 1.008g/mol, and oxygen is 16.00g/mol.
Find the MW of water by
2*(1.008) + (16.00) = 18.016g/mol.
Convert 1000g H2O to moles :
(1000g H2O)*(1mol H2O / 18.016g H2O) = 55.51 mol
Part B)
Using the answer from part A and Avogadro's number:
(55.51mol)*(6.022*10^23) =
3.343*10^25 molecules.

The moles of water will be 55.6 mole.
What is mole?
The SI standard unit of the material amount would be the mole, denoted by the sign mol. However many elementary organisms of a particular substance present in an object and sample are determined by the quantity of that material.
Calculation of mole.
Given data:
Volume = 1000 ml. = 1L
Density = 1000 kg/m3. = 1 g
The weight of water = 18 g/ mol.
1 g × 1 mol / 18 g = 1 / 18 mole
which will be equal to 0.0056 mole .
It will be 55.6 mole in 1 L.
Therefore, the moles of water will be 55.6 mole.
