The b.p. of a solution of 5g of sulphur in 100g of carbon disulphide is `0.476^(@)` above that of pure solvent. Determine the molecular formula of sulphur in this solvent. The b.p. of pure carbon disulphide is `46.30^(@)C` and its heat of vaporisation is `84.1` calories per gram.

Explanation

To determine the molecular formula of sulfur in the given solution, we will follow these steps:

### Step 1: Calculate the ebullioscopic constant (K_b) of carbon disulfide (CS2)

The formula for the ebullioscopic constant (K_b) is given by:

\[
K_b = \frac{RT_b^2}{\Delta H_{vap}}
