Molar and molecular weight of HLi

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

Calculation of the relative molecular and molar mass of HLi

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

HLi: percent composition by element

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