Molar and molecular weight of Zn3(PO4)2

• Molecular formula: Zn3(PO4)2 or O8P2Zn3
• Relative molecular weight of Zn3(PO4)2: 386.169724
• Molar mass of Zn3(PO4)2: 386.169724 g/mol (0.38617 kg/mol)

Calculation of the relative molecular and molar mass of Zn3(PO4)2

• Mr[Zn3(PO4)2] = Ar[O] * 8 + Ar[P] * 2 + Ar[Zn] * 3 = 15.9994 * 8 + 30.973762 * 2 + 65.409 * 3 = 386.169724
• Molar mass (kg/mol) = Mr[Zn3(PO4)2] : 1000 = 386.169724 : 1000 = 0.38617 kg/mol
