What volumes of 10 M HCl and 3 M HCl should be mixed to get 1L of 6 M HCl solution?

Explanation

To solve the problem of mixing two solutions of different molarities to achieve a desired molarity, we can follow these steps:

### Step 1: Define the Variables
Let:
- \( v_1 \) = volume of 10 M HCl (in liters)
- \( v_2 \) = volume of 3 M HCl (in liters)
- The total volume of the final solution \( v_3 = 1 \) L
- Molarities:
