Molar and molecular weight of Ce2S3

• Relative molecular weight of Ce2S3: 376.427
• Molar mass of Ce2S3: 376.427 g/mol (0.37643 kg/mol)

Calculation of the relative molecular and molar mass of Ce2S3

• Mr[Ce2S3] = Ar[Ce] * 2 + Ar[S] * 3 = 140.116 * 2 + 32.065 * 3 = 376.427
• Molar mass (kg/mol) = Mr[Ce2S3] : 1000 = 376.427 : 1000 = 0.37643 kg/mol

Ce2S3: percent composition by element

• Cerium (Ce) = 280.232 : 376.427 * 100 = 74.445 %
• Sulfur (S) = 96.195 : 376.427 * 100 = 25.555 %
