Answer:

The concentration is 0.111 M.

Explanation:

Use dimensional analysis to solve the problem. Since both HCl and NaOH are strong, the dissociate completely in solution.

For this neutralization, the reaction is HCl + NaOH = NaCl + HOH

18.5 mL x \frac{1 L}{1000 mL} x \frac{0.150 moles NaOH}{1 L} x \frac{1 mole HCl}{1 mole NaOH} = 0.002775 moles HCl

Molarity = moles/ Liters

Molarity of HCl = 0.002775 moles HCl / 0.025 L = 0.111 M
