The molar mass of Li2CO3 (Lithium Carbonate) is calculated by adding the atomic masses of all the atoms in the molecule. Here’s how it’s done:
- Lithium (Li) has an atomic mass of approximately 6.94 g/mol. Since there are two lithium atoms, the total mass for lithium is 2 × 6.94 = 13.88 g/mol.
- Carbon (C) has an atomic mass of approximately 12.01 g/mol. There is one carbon atom, so the mass for carbon is 12.01 g/mol.
- Oxygen (O) has an atomic mass of approximately 16.00 g/mol. There are three oxygen atoms, so the total mass for oxygen is 3 × 16.00 = 48.00 g/mol.
Adding these together, the molar mass of Li2CO3 is:
13.88 g/mol (Li) + 12.01 g/mol (C) + 48.00 g/mol (O) = 73.89 g/mol.
Therefore, the molar mass of Li2CO3 is 73.89 g/mol.
