In a acid-base titration, 22.81 mL of an NaOH solution were required to neutralize 26.18 mL of a 0.1121 M HCl solution. What is the molarity of the NaOH solution?
Write the equation to prove to yourself that it is 1 mole acid reacting with 1 mole base. That so, then
M1V1 = M2V2.
You have one unknown. Solve for that.
