Molar and molecular weight of KClO

• Molecular formula: KClO or ClKO
• Relative molecular weight of KClO: 90.5507
• Molar mass of KClO: 90.5507 g/mol (0.09055 kg/mol)

Calculation of the relative molecular and molar mass of KClO

• Mr[KClO] = Ar[Cl] + Ar[K] + Ar[O] = 35.453 + 39.0983 + 15.9994 = 90.5507
• Molar mass (kg/mol) = Mr[KClO] : 1000 = 90.5507 : 1000 = 0.09055 kg/mol

KClO: percent composition by element

• Chlorine (Cl) = 35.453 : 90.5507 * 100 = 39.153 %
• Potassium (K) = 39.0983 : 90.5507 * 100 = 43.178 %
• Oxygen (O) = 15.9994 : 90.5507 * 100 = 17.669 %
