Molar and molecular weight of Li2C2

• Molecular formula: Li2C2 or C2Li2
• Relative molecular weight of Li2C2: 37.9034
• Molar mass of Li2C2: 37.9034 g/mol (0.0379 kg/mol)

Calculation of the relative molecular and molar mass of Li2C2

• Mr[Li2C2] = Ar[C] * 2 + Ar[Li] * 2 = 12.0107 * 2 + 6.941 * 2 = 37.9034
• Molar mass (kg/mol) = Mr[Li2C2] : 1000 = 37.9034 : 1000 = 0.0379 kg/mol

Li2C2: percent composition by element

• Carbon (C) = 24.0214 : 37.9034 * 100 = 63.375 %
• Lithium (Li) = 13.882 : 37.9034 * 100 = 36.625 %
