Molar and molecular weight of IF3

• Molecular formula: IF3 or F3I
• Relative molecular weight of IF3: 183.8996796
• Molar mass of IF3: 183.8996796 g/mol (0.1839 kg/mol)

Calculation of the relative molecular and molar mass of IF3

• Mr[IF3] = Ar[F] * 3 + Ar[I] = 18.9984032 * 3 + 126.90447 = 183.8996796
• Molar mass (kg/mol) = Mr[IF3] : 1000 = 183.8996796 : 1000 = 0.1839 kg/mol

IF3: percent composition by element

• Fluorine (F) = 56.9952096 : 183.8996796 * 100 = 30.993 %
• Iodine (I) = 126.90447 : 183.8996796 * 100 = 69.007 %
