Molar and molecular weight of ClO2

• Relative molecular weight of ClO2: 67.4518
• Molar mass of ClO2: 67.4518 g/mol (0.06745 kg/mol)

Calculation of the relative molecular and molar mass of ClO2

• Mr[ClO2] = Ar[Cl] + Ar[O] * 2 = 35.453 + 15.9994 * 2 = 67.4518
• Molar mass (kg/mol) = Mr[ClO2] : 1000 = 67.4518 : 1000 = 0.06745 kg/mol

ClO2: percent composition by element

• Chlorine (Cl) = 35.453 : 67.4518 * 100 = 52.56 %
• Oxygen (O) = 31.9988 : 67.4518 * 100 = 47.44 %
