Molar and molecular weight of CeO2

• Relative molecular weight of CeO2: 172.1148
• Molar mass of CeO2: 172.1148 g/mol (0.17211 kg/mol)

Calculation of the relative molecular and molar mass of CeO2

• Mr[CeO2] = Ar[Ce] + Ar[O] * 2 = 140.116 + 15.9994 * 2 = 172.1148
• Molar mass (kg/mol) = Mr[CeO2] : 1000 = 172.1148 : 1000 = 0.17211 kg/mol

CeO2: percent composition by element

• Cerium (Ce) = 140.116 : 172.1148 * 100 = 81.408 %
• Oxygen (O) = 31.9988 : 172.1148 * 100 = 18.592 %
