    Molarity of HCl is 0.07 M.

    Explanation:

    Given dа ta:

    Molarity of NaOH = 0.10 M

    Volume of NaOH = 24.6 mL

    Molarity of HCl = ?

    Volume of HCl = 35.5 mL

    Solution:

    M (HCl) * V (HCl) = M (NaOH) * V (NaOH)

    M (HCl) = M (NaOH) * V (NaOH) / V (HCl)

    M (HCl) = 0.10 M * 24.6 mL / 35.5 mL

    M (HCl) = 2.46 M / 35.5

    M (HCl) = 0.07 M
