Molar and molecular weight of LiH

• Molecular formula: LiH or HLi
• Relative molecular weight of LiH: 7.94894
• Molar mass of LiH: 7.94894 g/mol (0.00795 kg/mol)

Calculation of the relative molecular and molar mass of LiH

• Mr[LiH] = Ar[H] + Ar[Li] = 1.00794 + 6.941 = 7.94894
• Molar mass (kg/mol) = Mr[LiH] : 1000 = 7.94894 : 1000 = 0.00795 kg/mol

LiH: percent composition by element

• Hydrogen (H) = 1.00794 : 7.94894 * 100 = 12.68 %
• Lithium (Li) = 6.941 : 7.94894 * 100 = 87.32 %
