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
