Benzene and toluene have equal mole fractions in their mutual solution. What do you expect about their mole fraction n the vapour phase at the same temperature? Explain.
(Given : `p_("Benzene")^(@)=3xxp_("Toluene")^(@)`)

Explanation

To solve the problem, we need to analyze the relationship between the mole fractions of benzene and toluene in both the liquid and vapor phases, given that their mole fractions in the liquid phase are equal.

### Step-by-Step Solution:

1. **Understanding the Given Information:**
We are given that benzene and toluene have equal mole fractions in their mutual solution. Let's denote the mole fraction of benzene as \( x_B \) and that of toluene as \( x_T \). Since they are equal, we can write:
\[
x_B = x_T
