`40ml 0.2 M H_(2)SO_(4)` is mixed with `50ml 0.3M H_(2)SO_(4)`. Find molarity
of final solution .

Explanation

To find the molarity of the final solution when mixing two solutions of sulfuric acid (H₂SO₄), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the given values:**
- Volume of first solution (V₁) = 40 mL = 40 × 10⁻³ L
- Molarity of first solution (M₁) = 0.2 M
- Volume of second solution (V₂) = 50 mL = 50 × 10⁻³ L
