Molar and molecular weight of Ce2O3

• Relative molecular weight of Ce2O3: 328.2302
• Molar mass of Ce2O3: 328.2302 g/mol (0.32823 kg/mol)

Calculation of the relative molecular and molar mass of Ce2O3

• Mr[Ce2O3] = Ar[Ce] * 2 + Ar[O] * 3 = 140.116 * 2 + 15.9994 * 3 = 328.2302
• Molar mass (kg/mol) = Mr[Ce2O3] : 1000 = 328.2302 : 1000 = 0.32823 kg/mol

Ce2O3: percent composition by element

• Cerium (Ce) = 280.232 : 328.2302 * 100 = 85.377 %
• Oxygen (O) = 47.9982 : 328.2302 * 100 = 14.623 %
