How many grams of sugar, `C_6H_12O_6` , should be dissolved in 0.5 kg of water at `25^@C` to reduce the vapour pressure of water by 1%?

Explanation

To solve the problem of how many grams of sugar (C₆H₁₂O₆) should be dissolved in 0.5 kg of water to reduce the vapor pressure of water by 1%, we can follow these steps:

### Step 1: Understand the concept of vapor pressure lowering
The lowering of vapor pressure can be described using Raoult's Law, which states that the relative lowering of vapor pressure is equal to the mole fraction of the solute.

### Step 2: Set up the equation
The formula for relative lowering of vapor pressure is:
\[
