Molar and molecular weight of NaClO2

• Molecular formula: NaClO2 or ClNaO2
• Relative molecular weight of NaClO2: 90.44156928
• Molar mass of NaClO2: 90.44156928 g/mol (0.09044 kg/mol)

Calculation of the relative molecular and molar mass of NaClO2

• Mr[NaClO2] = Ar[Cl] + Ar[Na] + Ar[O] * 2 = 35.453 + 22.98976928 + 15.9994 * 2 = 90.44156928
• Molar mass (kg/mol) = Mr[NaClO2] : 1000 = 90.44156928 : 1000 = 0.09044 kg/mol

NaClO2: percent composition by element

• Chlorine (Cl) = 35.453 : 90.44156928 * 100 = 39.2 %
• Sodium (Na) = 22.98976928 : 90.44156928 * 100 = 25.419 %
• Oxygen (O) = 31.9988 : 90.44156928 * 100 = 35.381 %
