Define osmotic pressure of a solution. How is the osmotic pressure orelated to the concentration of a solute in a solution ?

Explanation

**Step-by-Step Solution:**

1. **Definition of Osmotic Pressure:**
- Osmotic pressure is defined as the minimum external pressure that must be applied to a solution to prevent the flow of solvent into the solution through a semi-permeable membrane. This pressure is essential to counterbalance the natural tendency of solvent molecules to move into the solution, thereby maintaining equilibrium.

2. **Mathematical Representation:**
- Osmotic pressure (π) can be mathematically represented by the formula:
\[
