Molar and molecular weight of IF5

• Molecular formula: IF5 or F5I
• Relative molecular weight of IF5: 221.896486
• Molar mass of IF5: 221.896486 g/mol (0.2219 kg/mol)

Calculation of the relative molecular and molar mass of IF5

• Mr[IF5] = Ar[F] * 5 + Ar[I] = 18.9984032 * 5 + 126.90447 = 221.896486
• Molar mass (kg/mol) = Mr[IF5] : 1000 = 221.896486 : 1000 = 0.2219 kg/mol

IF5: percent composition by element

• Fluorine (F) = 94.992016 : 221.896486 * 100 = 42.809 %
• Iodine (I) = 126.90447 : 221.896486 * 100 = 57.191 %
