Molar and molecular weight of Li2CO3

• Molecular formula: Li2CO3 or CLi2O3
• Relative molecular weight of Li2CO3: 73.8909
• Molar mass of Li2CO3: 73.8909 g/mol (0.07389 kg/mol)

Calculation of the relative molecular and molar mass of Li2CO3

• Mr[Li2CO3] = Ar[C] + Ar[Li] * 2 + Ar[O] * 3 = 12.0107 + 6.941 * 2 + 15.9994 * 3 = 73.8909
• Molar mass (kg/mol) = Mr[Li2CO3] : 1000 = 73.8909 : 1000 = 0.07389 kg/mol

Li2CO3: percent composition by element

• Carbon (C) = 12.0107 : 73.8909 * 100 = 16.255 %
• Lithium (Li) = 13.882 : 73.8909 * 100 = 18.787 %
• Oxygen (O) = 47.9982 : 73.8909 * 100 = 64.958 %
