Using Raoult's law explain how the total vapour pressure over the solution is related to mole fraction of components in the following solutions.
(ii) `NaCl(s) and H_(2)O(l)`

Explanation

To explain how the total vapor pressure over a solution of NaCl and H₂O is related to the mole fraction of its components using Raoult's law, we can 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 directly proportional to its mole fraction in the solution. Mathematically, it can be expressed as:
\[ P_i = X_i \cdot P_i^0 \]
where:
- \( P_i \) is the partial vapor pressure of component \( i \),
- \( X_i \) is the mole fraction of component \( i \),
