Calculate the molality of potassium carbonate solution which is formed by dissolving 2.5 gm of it in one litre solution. (density of solution of 0.85 g/mL).

Explanation

To calculate the molality of the potassium carbonate solution, we will follow these steps:

### Step 1: Calculate the number of moles of potassium carbonate (K2CO3)
1. **Find the molar mass of potassium carbonate (K2CO3)**:
- Potassium (K) = 39.1 g/mol (2 atoms)
- Carbon (C) = 12.0 g/mol (1 atom)
- Oxygen (O) = 16.0 g/mol (3 atoms)
- Molar mass of K2CO3 = (2 × 39.1) + (1 × 12.0) + (3 × 16.0)
