A chemist performed a titration experiment in order to determine the concentration of a given aqueous solution of HCl (an acid). She pipeted 25.00 mL of the HCl solution into an Erlenmeyer flask. She then added about 15 mL of deionized water and 3 drops of phenolphthalein indicator dye to the flask. She titrated this mixture with 0.07533 M NaOH (aq), and obtained a permanent, pale pink endpoint after the addition of 22.81 mL of NaOH (aq). Given that the density of the HCl solution was 1.097 g/mL, determine the concentration of the original HCl acid solution in units of (a) Molarity (b) percent by mass
