What is the molarity of a NaOH solution if 50 mL is required to exactly react with 38.2 mL of 0.100 molar HCl?

Question

The balanced chemical equation for the reaction is NaOH + HCl → NaCl + H2O. This shows a 1:1 molar ratio between NaOH and HCl. Using the formula M1V1 = M2V2, where M1 and V1 are the molarity and volume of HCl, and M2 and V2 are the molarity and volume of NaOH, we have (0.100 M)(38.2 mL) = (M2)(50 mL). Solving for M2 gives M2 = 0.076 M.
