Find the ratio of volumes of `2M HNO_(3)` and `5M HNO_3 ` required to mix in order to prepare one litre of `3M HNO_3` solution.

Explanation

To find the ratio of volumes of `2M HNO₃` and `5M HNO₃` required to prepare one liter of `3M HNO₃` solution, we can follow these steps:

### Step 1: Define Variables
Let:
- \( V_1 \) = volume of `2M HNO₃` (in liters)
- \( V_2 \) = volume of `5M HNO₃` (in liters)

Since we want to prepare a total volume of 1 liter of `3M HNO₃`, we have:
