If `V_(1)mL` of `C_(1)` solution `+V_(2)mL` of `C_(2)` solution are mixed together then calculate final concentration of solution and final osmotic pressure. If initial osmotic pressure of two solutions are `pi_(1)` and `pi_(2)` respectively?

Explanation

To solve the problem, we need to find the final concentration of the mixed solution and the final osmotic pressure after mixing two solutions with given volumes and concentrations.

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Let \( V_1 \) be the volume of the first solution (in mL).
- Let \( C_1 \) be the concentration of the first solution (in mol/L).
- Let \( V_2 \) be the volume of the second solution (in mL).
