Answer the question
Which of the following solutions will have a lower vapour pressure and why?
(1) A 5% solution of cane sugar `(C_(12)H_(22)O_(11))`
(2) A 5% solution of urea `(NH_(2)CONH_(2))`

Explanation

To determine which of the two solutions has a lower vapor pressure, we can apply Raoult's Law, which states that the vapor pressure of a solvent is lowered when a solute is added. The extent of this lowering depends on the number of solute particles in the solution. Here’s how we can solve the problem step by step:

### Step 1: Identify the given solutions
We have two solutions:
1. A 5% solution of cane sugar (C₁₂H₂₂O₁₁)
2. A 5% solution of urea (NH₂CONH₂)

### Step 2: Understand the concept of vapor pressure lowering
