Molar and molecular weight of In2S3

• Relative molecular weight of In2S3: 325.831
• Molar mass of In2S3: 325.831 g/mol (0.32583 kg/mol)

Calculation of the relative molecular and molar mass of In2S3

• Mr[In2S3] = Ar[In] * 2 + Ar[S] * 3 = 114.818 * 2 + 32.065 * 3 = 325.831
• Molar mass (kg/mol) = Mr[In2S3] : 1000 = 325.831 : 1000 = 0.32583 kg/mol

In2S3: percent composition by element

• Indium (In) = 229.636 : 325.831 * 100 = 70.477 %
• Sulfur (S) = 96.195 : 325.831 * 100 = 29.523 %
