Molar and molecular weight of FePO4

• Molecular formula: FePO4 or FeO4P
• Relative molecular weight of FePO4: 150.816362
• Molar mass of FePO4: 150.816362 g/mol (0.15082 kg/mol)

Calculation of the relative molecular and molar mass of FePO4

• Mr[FePO4] = Ar[Fe] + Ar[O] * 4 + Ar[P] = 55.845 + 15.9994 * 4 + 30.973762 = 150.816362
• Molar mass (kg/mol) = Mr[FePO4] : 1000 = 150.816362 : 1000 = 0.15082 kg/mol

FePO4: percent composition by element

• Iron (Fe) = 55.845 : 150.816362 * 100 = 37.028 %
• Oxygen (O) = 63.9976 : 150.816362 * 100 = 42.434 %
• Phosphorus (P) = 30.973762 : 150.816362 * 100 = 20.537 %
