Molar and molecular weight of HIO4

• Relative molecular weight of HIO4: 191.91001
• Molar mass of HIO4: 191.91001 g/mol (0.19191 kg/mol)

Calculation of the relative molecular and molar mass of HIO4

• Mr[HIO4] = Ar[H] + Ar[I] + Ar[O] * 4 = 1.00794 + 126.90447 + 15.9994 * 4 = 191.91001
• Molar mass (kg/mol) = Mr[HIO4] : 1000 = 191.91001 : 1000 = 0.19191 kg/mol

HIO4: percent composition by element

• Hydrogen (H) = 1.00794 : 191.91001 * 100 = 0.525 %
• Iodine (I) = 126.90447 : 191.91001 * 100 = 66.127 %
• Oxygen (O) = 63.9976 : 191.91001 * 100 = 33.348 %
