How many moles of NaOH must be added to 200 mL of 0.1 M solution of `HNO_(3)` to get a solution having pH value 2.00 ?

Explanation

To determine how many moles of NaOH must be added to 200 mL of a 0.1 M solution of HNO₃ to achieve a solution with a pH of 2.00, we can follow these steps:

### Step 1: Calculate the moles of HNO₃ present in the solution
We know the concentration of HNO₃ and the volume of the solution.

- **Concentration (C) of HNO₃ = 0.1 M**
- **Volume (V) of HNO₃ = 200 mL = 0.2 L**
