What is Potassium Carbonate?

Potassium carbonate (K2CO3) is an inorganic compound that consists of potassium, carbon, and oxygen. It is a white, odorless, and hygroscopic salt, meaning it readily absorbs moisture from the air. This compound is widely used in various industries due to its alkaline properties and ability to neutralize acids.

Calculating the Molecular Mass of K2CO3

The molecular mass of a compound is determined by summing the atomic masses of all the atoms present in its formula. The molecular formula for potassium carbonate is K2CO3. To calculate the K2CO3 molecular mass, we need to know the atomic masses of potassium (K), carbon ©, and oxygen (O).

The atomic masses are approximately:

Potassium (K): 39.10 g/mol
Carbon (C): 12.01 g/mol
Oxygen (O): 16.00 g/mol

Using these values, we can calculate the molecular mass as follows:

Molecular mass of K2CO3 = (2 × atomic mass of K) + (1 × atomic mass of C) + (3 × atomic mass of O)

Molecular mass of K2CO3 = (2 × 39.10 g/mol) + (1 × 12.01 g/mol) + (3 × 16.00 g/mol)

Molecular mass of K2CO3 = 78.20 g/mol + 12.01 g/mol + 48.00 g/mol

Molecular mass of K2CO3 = 138.21 g/mol

Therefore, the K2CO3 molecular mass is approximately 138.21 grams per mole.
