If `6gm` of urea, `18gm` glucose `&` `34.2gm` surcose is dissolved to make `500mL` of a solution at `300K` calculate osmotic pressure?

Explanation

To calculate the osmotic pressure of the solution containing urea, glucose, and sucrose, we can follow these steps:

### Step 1: Calculate the number of moles for each solute.
The formula to calculate the number of moles (n) is:
\[ n = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} \]

1. **Urea**:
- Mass = 6 g
