Write expressions for the Raoult's law for non-volatile solutes.

Explanation

To write expressions for Raoult's law for non-volatile solutes, we will follow these steps:

### Step 1: Understand Raoult's Law
Raoult's law states that the partial vapor pressure of each component in a solution is equal to the vapor pressure of the pure component multiplied by its mole fraction in the solution.

### Step 2: Identify Components
In the case of non-volatile solutes, we have:
- Solvent (volatile)
