Which of the following colligative properties is affected by the number of solute particles in a solution?

Correct Answer: Vapor pressure lowering

Step 1: Understand what colligative properties are. These are properties of solutions that depend on the number of solute particles, not their identity.
Step 2: Identify the colligative properties. Common ones include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.
Step 3: Focus on vapor pressure lowering. This property occurs when a solute is added to a solvent, causing the vapor pressure of the solvent to decrease.
Step 4: Recognize that vapor pressure lowering is directly related to the number of solute particles in the solution. More solute particles lead to a greater decrease in vapor pressure.
Step 5: Conclude that vapor pressure lowering is the colligative property affected by the number of solute particles.
