• Molar mass of Na3PO4: 163.94066984 g/mol (0.16394 kg/mol)

Calculation of the relative molecular and molar mass of Na3PO4

• Mr[Na3PO4] = Ar[Na] * 3 + Ar[O] * 4 + Ar[P] = 22.98976928 * 3 + 15.9994 * 4 + 30.973762 = 163.94066984
• Molar mass (kg/mol) = Mr[Na3PO4] : 1000 = 163.94066984 : 1000 = 0.16394 kg/mol

Na3PO4: percent composition by element

• Sodium (Na) = 68.96930784 : 163.94066984 * 100 = 42.07 %
