Molar and molecular weight of Al2S3

• Relative molecular weight of Al2S3: 150.1580772
• Molar mass of Al2S3: 150.1580772 g/mol (0.15016 kg/mol)

Calculation of the relative molecular and molar mass of Al2S3

• Mr[Al2S3] = Ar[Al] * 2 + Ar[S] * 3 = 26.9815386 * 2 + 32.065 * 3 = 150.1580772
• Molar mass (kg/mol) = Mr[Al2S3] : 1000 = 150.1580772 : 1000 = 0.15016 kg/mol

Al2S3: percent composition by element

• Aluminum (Al) = 53.9630772 : 150.1580772 * 100 = 35.938 %
• Sulfur (S) = 96.195 : 150.1580772 * 100 = 64.062 %
