Sodium Phosphate Dibasic Dihydrate [Na2HPO4.2H2O] Molecular Weight Calculation
Sodium phosphate dibasic (Na2HPO4), also called Disodium phosphate (DSP) or disodium hydrogen phosphate, is an inorganic compound of four elements: Sodium, Hydrogen, Phosphorus, and Oxygen. The dihydrate form of Sodium phosphate dibasic (Na2HPO4.2H2O) also contains 2 water molecules. The molecular weight of Sodium phosphate dibasic dihydrate is 177.9897 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements and water molecules.
