Molar and molecular weight of F5I

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

Calculation of the relative molecular and molar mass of F5I

• Mr[F5I] = Ar[F] * 5 + Ar[I] = 18.9984032 * 5 + 126.90447 = 221.896486
• Molar mass (kg/mol) = Mr[F5I] : 1000 = 221.896486 : 1000 = 0.2219 kg/mol

F5I: percent composition by element

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