Molar and molecular weight of COS

• Relative molecular weight of COS: 60.0751
• Molar mass of COS: 60.0751 g/mol (0.06008 kg/mol)

Calculation of the relative molecular and molar mass of COS

• Mr[COS] = Ar[C] + Ar[O] + Ar[S] = 12.0107 + 15.9994 + 32.065 = 60.0751
• Molar mass (kg/mol) = Mr[COS] : 1000 = 60.0751 : 1000 = 0.06008 kg/mol

COS: percent composition by element

• Carbon (C) = 12.0107 : 60.0751 * 100 = 19.993 %
• Oxygen (O) = 15.9994 : 60.0751 * 100 = 26.632 %
• Sulfur (S) = 32.065 : 60.0751 * 100 = 53.375 %
