The molarity of 15.0 mL HCl solution that requires 18.40 mL of 0.10 M NaOH to reach endpoint will be 0.12 M

Molarity

From the equation of the reaction:

HCl + NaOH -----------. NaCl + H2O

Mole ratio of acid and base = 1:1

Using the equation: MaVa/MbVb = 1/1

where Ma = molarity of acid, Va = volume of acid, Mb = molarity of base, and Vb = volume of base.

Ma = MbVb/Va

               = 0.1 x 18.40/15.0

                       = 0.12 M
