Calculate the molar mass of a substance `1 g` of which when dissolved in `100 g ` of water gave a solution boiling at `100.1^(@)C` at a pressure of 1 atm `(K_(b)` for water `= 0.52 K kg mol^(-1))`

Explanation

To calculate the molar mass of the substance, we will follow these steps:

### Step 1: Determine the boiling point elevation (ΔTb)
The boiling point of the solution is given as 100.1°C. The boiling point of pure water is 100°C. Therefore, the elevation in boiling point (ΔTb) can be calculated as:

\[ \Delta T_b = T_{b,\text{solution}} - T_{b,\text{water}} = 100.1°C - 100°C = 0.1°C \]
