Calculate the molecular mass of a substance 1.0 g of which on being dissolved in 100 g of solvent gave an elevation of 0.307 K in the boiling point. (Molal elevation constant `(k_b)=1.84 K//m`.

Explanation

To calculate the molecular mass of the substance, we can follow these steps:

### Step 1: Write down the formula for boiling point elevation
The elevation in boiling point (\( \Delta T_b \)) is related to the molal elevation constant (\( K_b \)) and the molality (\( m \)) of the solution by the formula:
\[ \Delta T_b = K_b \times m \]
