Molar and molecular weight of HIO3

• Relative molecular weight of HIO3: 175.91061
• Molar mass of HIO3: 175.91061 g/mol (0.17591 kg/mol)

Calculation of the relative molecular and molar mass of HIO3

• Mr[HIO3] = Ar[H] + Ar[I] + Ar[O] * 3 = 1.00794 + 126.90447 + 15.9994 * 3 = 175.91061
• Molar mass (kg/mol) = Mr[HIO3] : 1000 = 175.91061 : 1000 = 0.17591 kg/mol

HIO3: percent composition by element

• Hydrogen (H) = 1.00794 : 175.91061 * 100 = 0.573 %
• Iodine (I) = 126.90447 : 175.91061 * 100 = 72.141 %
• Oxygen (O) = 47.9982 : 175.91061 * 100 = 27.286 %
