Molar and molecular weight of LiCl

• Molecular formula: LiCl or ClLi
• Relative molecular weight of LiCl: 42.394
• Molar mass of LiCl: 42.394 g/mol (0.04239 kg/mol)

Calculation of the relative molecular and molar mass of LiCl

• Mr[LiCl] = Ar[Cl] + Ar[Li] = 35.453 + 6.941 = 42.394
• Molar mass (kg/mol) = Mr[LiCl] : 1000 = 42.394 : 1000 = 0.04239 kg/mol

LiCl: percent composition by element

• Chlorine (Cl) = 35.453 : 42.394 * 100 = 83.627 %
• Lithium (Li) = 6.941 : 42.394 * 100 = 16.373 %
