Molar and molecular weight of Zn2P2O7

• Relative molecular weight of Zn2P2O7: 304.761324
• Molar mass of Zn2P2O7: 304.761324 g/mol (0.30476 kg/mol)

Calculation of the relative molecular and molar mass of Zn2P2O7

• Mr[Zn2P2O7] = Ar[Zn] * 2 + Ar[P] * 2 + Ar[O] * 7 = 65.409 * 2 + 30.973762 * 2 + 15.9994 * 7 = 304.761324
• Molar mass (kg/mol) = Mr[Zn2P2O7] : 1000 = 304.761324 : 1000 = 0.30476 kg/mol
