What is Calcium Carbonate?
Calcium carbonate (CaCO₃) is a versatile chemical compound used in numerous applications, from construction materials to pharmaceuticals. It naturally occurs in various forms, including limestone, marble, and chalk. Its industrial significance stems from its use as a filler in products such as paper, paint, and plastics, as well as its role in water treatment and as a dietary supplement.
Understanding the Molar Mass of Calcium Carbonate
Definition and Calculation
The molar mass of calcium carbonate is the sum of the atomic masses of all the atoms present in one mole of the compound. Calcium carbonate has a chemical formula of CaCO₃, consisting of one calcium atom, one carbon atom, and three oxygen atoms. To calculate its molar mass, you need to add up the atomic masses of these elements.
- Calcium (Ca): The atomic mass of calcium is approximately 40.08 g/mol.
- Carbon (C): The atomic mass of carbon is approximately 12.01 g/mol.
- Oxygen (O): The atomic mass of oxygen is approximately 16.00 g/mol.
The formula for calculating the molar mass of calcium carbonate is:
1. Finding the Molar Mass of CaCO₃
The molar mass of calcium carbonate (CaCO₃) is calculated by summing the atomic masses of its constituent elements:
- Calcium (Ca): Atomic mass = 40.08 g/mol
- Carbon (C): Atomic mass = 12.01 g/mol
The chemical formula for calcium carbonate is CaCO₃, which means it contains:
- 1 atom of Calcium
- 1 atom of Carbon
- 3 atoms of Oxygen
To find the molar mass:
Molar Mass=(1×Atomic Mass of Ca)+(1×Atomic Mass of C)+(3×Atomic Mass of O)\text{Molar Mass} = (1 \times \text{Atomic Mass of Ca}) + (1 \times \text{Atomic Mass of C}) + (3 \times \text{Atomic Mass of O})Molar Mass=(1×Atomic Mass of Ca)+(1×Atomic Mass of C)+(3×Atomic Mass of O)
Molar Mass=(1×40.08)+(1×12.01)+(3×16.00)\text{Molar Mass} = (1 \times 40.08) + (1 \times 12.01) + (3 \times 16.00)Molar Mass=(1×40.08)+(1×12.01)+(3×16.00)
Molar Mass=40.08+12.01+48.00\text{Molar Mass} = 40.08 + 12.01 + 48.00Molar Mass=40.08+12.01+48.00
Molar Mass=100.09 g/mol\text{Molar Mass} = 100.09 \text{ g/mol}Molar Mass=100.09 g/mol
2. Molar Mass of Carbonate Ion (CO₃²⁻)
The carbonate ion (CO₃²⁻) has the following composition:
- Carbon (C): Atomic mass = 12.01 g/mol
- Oxygen (O): Atomic mass = 16.00 g/mol (3 atoms)
The molar mass is calculated as:
Molar Mass of CO32−=(1×Atomic Mass of C)+(3×Atomic Mass of O)\text{Molar Mass of CO}_3^{2-} = (1 \times \text{Atomic Mass of C}) + (3 \times \text{Atomic Mass of O})Molar Mass of CO32−=(1×Atomic Mass of C)+(3×Atomic Mass of O)
Molar Mass of CO32−=(1×12.01)+(3×16.00)\text{Molar Mass of CO}_3^{2-} = (1 \times 12.01) + (3 \times 16.00)Molar Mass of CO32−=(1×12.01)+(3×16.00)
Molar Mass of CO32−=12.01+48.00\text{Molar Mass of CO}_3^{2-} = 12.01 + 48.00Molar Mass of CO32−=12.01+48.00
Molar Mass of CO32−=60.01 g/mol\text{Molar Mass of CO}_3^{2-} = 60.01 \text{ g/mol}Molar Mass of CO32−=60.01 g/mol
3. Molar Mass of 2CaCO₃
For 2 moles of calcium carbonate (2CaCO₃), simply multiply the molar mass of one mole of CaCO₃ by 2:
Molar Mass of 2CaCO3=2×Molar Mass of CaCO3\text{Molar Mass of 2CaCO}_3 = 2 \times \text{Molar Mass of CaCO}_3Molar Mass of 2CaCO3=2×Molar Mass of CaCO3
Molar Mass of 2CaCO3=2×100.09\text{Molar Mass of 2CaCO}_3 = 2 \times 100.09Molar Mass of 2CaCO3=2×100.09
Molar Mass of 2CaCO3=200.18 g/mol\text{Molar Mass of 2CaCO}_3 = 200.18 \text{ g/mol}Molar Mass of 2CaCO3=200.18 g/mol
