Molar and molecular weight of HClO2

• Molecular formula: HClO2 or HOClO
• Relative molecular weight of HClO2: 68.45974
• Molar mass of HClO2: 68.45974 g/mol (0.06846 kg/mol)

Calculation of the relative molecular and molar mass of HClO2

• Mr[HClO2] = Ar[H] + Ar[Cl] + Ar[O] * 2 = 1.00794 + 35.453 + 15.9994 * 2 = 68.45974
• Molar mass (kg/mol) = Mr[HClO2] : 1000 = 68.45974 : 1000 = 0.06846 kg/mol

HClO2: percent composition by element

• Hydrogen (H) = 1.00794 : 68.45974 * 100 = 1.472 %
• Chlorine (Cl) = 35.453 : 68.45974 * 100 = 51.787 %
• Oxygen (O) = 31.9988 : 68.45974 * 100 = 46.741 %
