The molar mass of CaCO3 (Calcium Carbonate) is calculated by adding the atomic masses of its constituent elements: Calcium (Ca), Carbon (C), and Oxygen (O).
Here’s the breakdown:
- Calcium (Ca) has an atomic mass of approximately 40.08 g/mol.
- Carbon (C) has an atomic mass of approximately 12.01 g/mol.
- Oxygen (O) has an atomic mass of approximately 16.00 g/mol. Since there are three oxygen atoms in CaCO3, we multiply 16.00 by 3, which gives us 48.00 g/mol.
Now, we add these values together:
40.08 (Ca) + 12.01 (C) + 48.00 (O) = 100.09 g/mol
Therefore, the molar mass of CaCO3 is 100.09 g/mol.
