    Answer: There are 20 milliliters of 1.0 M HCl is required to be diluted to make 200 mL of a 0.1 M solution.

    Explanation:

    Given: M_{1} = 1.0 M,    V_{1} = ?

    M_{2} = 0.1 M,    V_{2} = 200 mL

    Formula used is as follows.

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

    Substitute values into the above formula as follows.

    M_{1}V_{1} = M_{2}V_{2}\\1.0 M \times V_{1} = 0.1 M \times 200 mL\\V_{1} = \frac{0.1 M \times 200 mL}{1.0 M}\\= 20 mL

    Thus, we can conclude that there are 20 milliliters of 1.0 M HCl is required to be diluted to make 200 mL of a 0.1 M solution.
