Molar and molecular weight of Ca3(PO4)2

• Molecular formula: Ca3(PO4)2 or Ca3O8P2
• Relative molecular weight of Ca3(PO4)2: 310.176724
• Molar mass of Ca3(PO4)2: 310.176724 g/mol (0.31018 kg/mol)

Calculation of the relative molecular and molar mass of Ca3(PO4)2

• Mr[Ca3(PO4)2] = Ar[Ca] * 3 + Ar[O] * 8 + Ar[P] * 2 = 40.078 * 3 + 15.9994 * 8 + 30.973762 * 2 = 310.176724
• Molar mass (kg/mol) = Mr[Ca3(PO4)2] : 1000 = 310.176724 : 1000 = 0.31018 kg/mol

Ca3(PO4)2: percent composition by element
