Calculate the molar mass of a substance 1.3 g of which when dissolved in 169 g of water gave a solution boiling at `100.025^(@)C` at a pressure of one atmosphere (`K_(b)` for water = `"0.52 K m"^(-1)`)

Explanation

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

### Step 1: Determine the elevation in boiling point (ΔT_b)
The elevation in boiling point is calculated as follows:
\[ \Delta T_b = T_{b,\text{solution}} - T_{b,\text{solvent}} \]
Given:
...
