Molar and molecular weight of FeF3

• Molecular formula: FeF3 or F3Fe
• Relative molecular weight of FeF3: 112.8402096
• Molar mass of FeF3: 112.8402096 g/mol (0.11284 kg/mol)

Calculation of the relative molecular and molar mass of FeF3

• Mr[FeF3] = Ar[F] * 3 + Ar[Fe] = 18.9984032 * 3 + 55.845 = 112.8402096
• Molar mass (kg/mol) = Mr[FeF3] : 1000 = 112.8402096 : 1000 = 0.11284 kg/mol

FeF3: percent composition by element

• Fluorine (F) = 56.9952096 : 112.8402096 * 100 = 50.51 %
• Iron (Fe) = 55.845 : 112.8402096 * 100 = 49.49 %
