Molecular Mass Of Calcium Carbonate
Molecular Mass Of Calcium Carbonate: The molecular mass of calcium carbonate, often referred to as calcium carbonate’s molar mass, is a fundamental concept in chemistry.
It plays a crucial role in various scientific fields, including chemistry, geology, environmental science, and industry. In this article, we will explore what the molecular mass of calcium carbonate is, how it is calculated, its significance, and its practical applications.
Molecular Mass Of Calcium Carbonate
Defining Molecular Mass
The molecular mass, also known as molar mass, of a compound is the mass of one mole of that substance expressed in grams per mole (g/mol). In the case of calcium carbonate (CaCO3), its molecular mass represents the combined mass of one mole of calcium (Ca) atoms, one mole of carbon (C) atoms, and three moles of oxygen (O) atoms.
Calculation of Molecular Mass
To calculate the mole mass of calcium carbonate (CaCO3), we sum the atomic masses of its constituent elements:
- Calcium (Ca): Atomic mass ≈ 40.08 g/mol
- Carbon (C): Atomic mass ≈ 12.01 g/mol
- Oxygen (O): Atomic mass ≈ 16.00 g/mol
Now, let’s calculate the mole mass of CaCO3:
Molecular Mass of CaCO3 = (Molar Mass of Ca) + (Molar Mass of C) + (3 × Molar Mass of O)
The Molecular Mass of CaCO3 = (40.08 g/mol) + (12.01 g/mol) + (3 × 16.00 g/mol)
Molecular Mass of CaCO3 ≈ 100.09 g/mol
Therefore, the mole mass of calcium carbonate (CaCO3) is approximately 100.09 grams per mole.
