What is the molarity of a solution of HCl if 5.00 mL of the HCl solution is
titrated with 28.6 mL of a 0.145 M NaOH solution?

Round your answer to 3
decimal places.

HCl + NaOH → NaCl + H 2 O

The molarity of the HCl is 0.8924 M.

Explanation:

Use dimensional analysis to solve the problem.

28.6 mL x () x () x () = 0.004147 moles HCl

Then we use M= moles/ liter  to find the molarity.

M = 0.004147 moles HCl / 0.005 L

M = 0.8294
