Why is osmotic pressure considered as colligative property?

Explanation

**Step-by-Step Solution:**

1. **Definition of Colligative Property**:
- A colligative property is a property of a solution that depends on the number of solute particles in a given amount of solvent, rather than the identity of the solute.

2. **Understanding Osmotic Pressure**:
- Osmotic pressure (π) is the pressure required to stop the flow of solvent into a solution through a semipermeable membrane. It is a measure of the tendency of a solvent to move into a solution.
