Question

You are given a solution of 0.170M naoh and asked to find the molarity
of an unknown HBr solution. 11.29mL of naoh was used to reach the
endpoint when 38.55 mL of HBr was titrated. What is the molarity of
the HBr solution

Accepted Answer

NaOH + HBr = NaBr + H2O

11.29 x 0.17 / 38.55 = 0.05 M.
