Molar and molecular weight of Fe3(PO4)2

• Molecular formula: Fe3(PO4)2 or Fe3O8P2
• Relative molecular weight of Fe3(PO4)2: 357.477724
• Molar mass of Fe3(PO4)2: 357.477724 g/mol (0.35748 kg/mol)

Calculation of the relative molecular and molar mass of Fe3(PO4)2

• Mr[Fe3(PO4)2] = Ar[Fe] * 3 + Ar[O] * 8 + Ar[P] * 2 = 55.845 * 3 + 15.9994 * 8 + 30.973762 * 2 = 357.477724
• Molar mass (kg/mol) = Mr[Fe3(PO4)2] : 1000 = 357.477724 : 1000 = 0.35748 kg/mol
