    Answer:

    53.2 mL

    Explanation:

    As this problem deals with the neutralization of a strong monoprotic acid and a strong base, we can solve it by using the following formula:

    • Ca * Va = Cb * Vb

    Where in this case:

    • Ca = 0.230 M
    • Va = 74.0 mL
    • Cb = 0.320 M
    • Vb = ?

    We input the data:

    • 0.230 M * 74.0 mL = 0.320 M * Vb

    And solve for Vb:

    • Vb = 53.2 mL
