Molar and molecular weight of Sr3(PO4)2

• Molecular formula: Sr3(PO4)2 or O8P2Sr3
• Relative molecular weight of Sr3(PO4)2: 452.802724
• Molar mass of Sr3(PO4)2: 452.802724 g/mol (0.4528 kg/mol)

Calculation of the relative molecular and molar mass of Sr3(PO4)2

• Mr[Sr3(PO4)2] = Ar[O] * 8 + Ar[P] * 2 + Ar[Sr] * 3 = 15.9994 * 8 + 30.973762 * 2 + 87.62 * 3 = 452.802724
• Molar mass (kg/mol) = Mr[Sr3(PO4)2] : 1000 = 452.802724 : 1000 = 0.4528 kg/mol
