Molar mass of Na2HPO4 = 142 Molar mass of Na2HPO4.2H2O = 142+36= 178 Molar mass of Na2HPO4.7H2O = 142+126= 268. The molar mass is used to convert between grams and moles and the unit is g/mol. Here, for example, one mole of Na2HPO4 (acting as acid) can dissociate to give one mole H+ ions, therefore n-factor is 1. Determine the mass of Na3PO4 X 12H2O in the salt mixture. This compound is also known as Disodium Phosphate. itself which is roughly 142.
