Calculate the vapour pressure lowering caused by addition of `50g` of sucrose (molecular mass `= 342)` to `500g` of water if the vapour pressure of pure water at `25^(@)C` is `23.8 mm Hg`.

Explanation

To calculate the vapor pressure lowering caused by the addition of 50 g of sucrose to 500 g of water, we can follow these steps:

### Step 1: Calculate the moles of sucrose (solute).
The formula to calculate moles is:
\[ \text{Moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} \]
For sucrose:
...
