Assuming ideal behaviour, calculate the vapour pressure of 1.0 molal solution of a non-volatile molecular solute in water at `50^@C` . The vapour pressure of water at `50^@C` is 0.122 atm.

Explanation

To calculate the vapor pressure of a 1.0 molal solution of a non-volatile molecular solute in water at 50°C, we can follow these steps:

### Step 1: Understand the given information
- The vapor pressure of pure water (P₀) at 50°C is given as 0.122 atm.
- The molality (m) of the solution is 1.0 molal.

### Step 2: Use Raoult's Law
Raoult's Law states that the vapor pressure of a solvent in a solution is equal to the vapor pressure of the pure solvent multiplied by its mole fraction in the solution. The formula can be expressed as:
...
