Molar and molecular weight of Cl2O

• Relative molecular weight of Cl2O: 86.9054
• Molar mass of Cl2O: 86.9054 g/mol (0.08691 kg/mol)

Calculation of the relative molecular and molar mass of Cl2O

• Mr[Cl2O] = Ar[Cl] * 2 + Ar[O] = 35.453 * 2 + 15.9994 = 86.9054
• Molar mass (kg/mol) = Mr[Cl2O] : 1000 = 86.9054 : 1000 = 0.08691 kg/mol

Cl2O: percent composition by element

• Chlorine (Cl) = 70.906 : 86.9054 * 100 = 81.59 %
• Oxygen (O) = 15.9994 : 86.9054 * 100 = 18.41 %
