    Answer: New volume of the solution is 100 mL.

    Explanation:

    Given: V_{1} = 3 mL,     M_{1} = 200 M

    M_{2} = 6 M,     V_2 = ?

    Formula used to calculate the new volume of solution is as follows.

    M_{1}V_{1} = M_{2}V_{2}

    Substitute the values into above formula as follows.

    M_{1}V_{1} = M_{2}V_{2}\\200 M \times 3 mL = 6 M \times V_{2}\\V_{2} = \frac{200 M \times 3 mL}{6 M}\\= 100 mL

    Thus, we can conclude that new volume of the solution is 100 mL.
