Two liquids `A` and `B` form an ideal soluton. The vapour pressure of pure `A` and pure `B` are `66 mm Hg` and `88 mm Hg`, respectively. Calculate the composition of vapour `A` in the solution which is equilbrium and whose molar volume is `36%`.

Options

A. 0.43
B. 0.7
C. 0.3
D. 0.5

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the Given Data
We have two liquids, A and B, that form an ideal solution. The vapor pressures of pure A and pure B are given as:
- \( P_{A}^{0} = 66 \, \text{mm Hg} \)
- \( P_{B}^{0} = 88 \, \text{mm Hg} \)

The molar volume of the solution is given as \( 36\% \) or \( 0.36 \).
