Molar and molecular weight of HF

• Relative molecular weight of HF: 20.0063432
• Molar mass of HF: 20.0063432 g/mol (0.02001 kg/mol)

Calculation of the relative molecular and molar mass of HF

• Mr[HF] = Ar[H] + Ar[F] = 1.00794 + 18.9984032 = 20.0063432
• Molar mass (kg/mol) = Mr[HF] : 1000 = 20.0063432 : 1000 = 0.02001 kg/mol

HF: percent composition by element

• Hydrogen (H) = 1.00794 : 20.0063432 * 100 = 5.038 %
• Fluorine (F) = 18.9984032 : 20.0063432 * 100 = 94.962 %
