First you need to calculate the molar mass of H2O. To do that, look at the periodic table and add up the AMUs (atomic mass units)
H = 1.01
O = 16.0
1.01 • 2 + 16.0 = 18.02
Next, use stoichiometry to convert grams into moles. To do that, divide 814.504g by the number of grams in one mole of H2O.
814.504 : 18.02 = 45.2 moles
There are 45.2 moles in 814.504 grams of H2O.
