A chemist had a bottle of HCl (aq) of unknown concentration. She performed a titration experiment in order to determine its concentration. She pipetted 12.55 mL of the HCl solution into an Erlenmeyer flask. She then added about 21 mL of deionized water and 3 drops of phenolphthalein indicator dye to the flask. She titrated this mixture with 0.0716 M NaOH (aq), and obtained a permanent, pale pink endpoint after the addition of 23.16 mL of NaOH (aq). Calculate the molarity of the HCl solution and report your final answer with units and the correct significant digits.
