2 g each of the solutes A and B ( mol mass of A gt B)
are dissolved separately in 20 g each of the same solvent C. Which
will show gr eater lowering of vapour pressure and why ?

Explanation

To determine which solute (A or B) will show a greater lowering of vapor pressure when dissolved in the same solvent, we can follow these steps:

### Step 1: Understand the Concept of Lowering of Vapor Pressure
Lowering of vapor pressure is a colligative property, which means it depends on the number of solute particles in a solution rather than the identity of the solute.

### Step 2: Calculate the Number of Moles of Each Solute
We can calculate the number of moles of each solute (A and B) using the formula:
\[
