5. When performing a titration, a student adds three drops of phenolphthalein to a flask containing 40.1 mL of HCl. Using a buret, the student slowly adds 2 M NaOH to the flask until one drop causes the
indicator to turn light pink. The student determines that a total volume of 24.2 mL of NaOH was used
in this titration. Calculate the molarity of the HCl used in the titration. (2p)
