Molar and molecular weight of LiF

• Molecular formula: LiF or FLi
• Relative molecular weight of LiF: 25.9394032
• Molar mass of LiF: 25.9394032 g/mol (0.02594 kg/mol)

Calculation of the relative molecular and molar mass of LiF

• Mr[LiF] = Ar[F] + Ar[Li] = 18.9984032 + 6.941 = 25.9394032
• Molar mass (kg/mol) = Mr[LiF] : 1000 = 25.9394032 : 1000 = 0.02594 kg/mol

LiF: percent composition by element

• Fluorine (F) = 18.9984032 : 25.9394032 * 100 = 73.241 %
• Lithium (Li) = 6.941 : 25.9394032 * 100 = 26.759 %
