Molar and molecular weight of CeS

• Relative molecular weight of CeS: 172.181
• Molar mass of CeS: 172.181 g/mol (0.17218 kg/mol)

Calculation of the relative molecular and molar mass of CeS

• Mr[CeS] = Ar[Ce] + Ar[S] = 140.116 + 32.065 = 172.181
• Molar mass (kg/mol) = Mr[CeS] : 1000 = 172.181 : 1000 = 0.17218 kg/mol

CeS: percent composition by element

• Cerium (Ce) = 140.116 : 172.181 * 100 = 81.377 %
• Sulfur (S) = 32.065 : 172.181 * 100 = 18.623 %
