The molar mass of K2SO4 (Potassium Sulfate) is calculated by adding the atomic masses of its constituent elements. Here’s how it’s done:
- Potassium (K) has an atomic mass of approximately 39.1 g/mol.
- Sulfur (S) has an atomic mass of approximately 32.1 g/mol.
- Oxygen (O) has an atomic mass of approximately 16.0 g/mol.
In K2SO4, there are 2 potassium atoms, 1 sulfur atom, and 4 oxygen atoms. Therefore, the molar mass is calculated as follows:
Molar Mass = (2 × 39.1) + (1 × 32.1) + (4 × 16.0)
Molar Mass = 78.2 + 32.1 + 64.0
Molar Mass = 174.3 g/mol
So, the molar mass of K2SO4 is 174.3 g/mol.
