Na2SO4 = 46+32+64 = 142

Na = 46/142 * 100 = 32.39 %

S = 32/142 * 100 = 22.54 %

O = 64/142 * 100 = 45.08 %

The molar mass of dibasic sodium phosphate or (Na2HPO4) is 141.96 grams/mole.The molar masses of the individual elements are:Na= 22.99 grams H= 1.008 grams P= 30.97 grams O= 16.00 grams Now just divide the mass of each element present in the compound by the molar mass and multiply by 100 for the percent composition.
