Calculate the molal elevation constant of water, it being given that 0.1 molal aqueous solution of a substance boiled at `100.052^(@)C`.

Explanation

To calculate the molal elevation constant (K_b) of water, we can follow these steps:

### Step 1: Identify the given data
- Molality (M) of the solution = 0.1 molal
- Boiling point of the solution (T_solution) = 100.052 °C
- Boiling point of pure solvent (T_solvent, water) = 100 °C

### Step 2: Calculate the change in boiling point (ΔT_b)
