Molar and molecular weight of KIO3

• Molecular formula: KIO3 or IKO3
• Relative molecular weight of KIO3: 214.00097
• Molar mass of KIO3: 214.00097 g/mol (0.214 kg/mol)

Calculation of the relative molecular and molar mass of KIO3

• Mr[KIO3] = Ar[I] + Ar[K] + Ar[O] * 3 = 126.90447 + 39.0983 + 15.9994 * 3 = 214.00097
• Molar mass (kg/mol) = Mr[KIO3] : 1000 = 214.00097 : 1000 = 0.214 kg/mol

KIO3: percent composition by element

• Iodine (I) = 126.90447 : 214.00097 * 100 = 59.301 %
• Potassium (K) = 39.0983 : 214.00097 * 100 = 18.27 %
• Oxygen (O) = 47.9982 : 214.00097 * 100 = 22.429 %
