Molar and molecular weight of F3I

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

Calculation of the relative molecular and molar mass of F3I

• Mr[F3I] = Ar[F] * 3 + Ar[I] = 18.9984032 * 3 + 126.90447 = 183.8996796
• Molar mass (kg/mol) = Mr[F3I] : 1000 = 183.8996796 : 1000 = 0.1839 kg/mol

F3I: percent composition by element

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