Molar and molecular weight of Fe2(CrO4)3

• Molecular formula: Fe2(CrO4)3 or Cr3Fe2O12
• Relative molecular weight of Fe2(CrO4)3: 459.6711
• Molar mass of Fe2(CrO4)3: 459.6711 g/mol (0.45967 kg/mol)

Calculation of the relative molecular and molar mass of Fe2(CrO4)3

• Mr[Fe2(CrO4)3] = Ar[Cr] * 3 + Ar[Fe] * 2 + Ar[O] * 12 = 51.9961 * 3 + 55.845 * 2 + 15.9994 * 12 = 459.6711
• Molar mass (kg/mol) = Mr[Fe2(CrO4)3] : 1000 = 459.6711 : 1000 = 0.45967 kg/mol
