Molar and molecular weight of SO2Cl2

• Molecular formula: SO2Cl2 or Cl2O2S
• Relative molecular weight of SO2Cl2: 134.9698
• Molar mass of SO2Cl2: 134.9698 g/mol (0.13497 kg/mol)

Calculation of the relative molecular and molar mass of SO2Cl2

• Mr[SO2Cl2] = Ar[Cl] * 2 + Ar[O] * 2 + Ar[S] = 35.453 * 2 + 15.9994 * 2 + 32.065 = 134.9698
• Molar mass (kg/mol) = Mr[SO2Cl2] : 1000 = 134.9698 : 1000 = 0.13497 kg/mol

SO2Cl2: percent composition by element

• Chlorine (Cl) = 70.906 : 134.9698 * 100 = 52.535 %
• Oxygen (O) = 31.9988 : 134.9698 * 100 = 23.708 %
• Sulfur (S) = 32.065 : 134.9698 * 100 = 23.757 %
