In terms of osmotic pressure `(pi)` and volume of the solution (V) containing n moles of the solute, van't Hoff factor (i) at temperature T = …………….. .

Explanation

To derive the expression for the van't Hoff factor (i) in terms of osmotic pressure (π), volume of the solution (V), number of moles of solute (n), and temperature (T), we can follow these steps:

### Step 1: Understand the relationship of osmotic pressure
The osmotic pressure (π) of a solution can be expressed using the formula:
\[ \pi = iCRT \]
where:
