A chemist performed a titration experiment in order to determine the concentration of a givenaqueous solution of HCl (an acid). She pipeted 15.00 mL of the HCl solution into anErlenmeyer flask. She then added about 20 mL of deionized water and 3 drops ofphenolphthalein indicator dye to the flask. She titrated this mixture with 0.07269 M NaOH(aq), and obtained a permanent, pale pink endpoint after the addition of 24.33 mL of NaOH(aq). Given that the density of the HCl solution was 1.095 g/mL, determine the concentrationof the original HCl acid solution in units ofa) Molarityb) Percent by mass (Hint: refer to Skill Builder 6 to see the relationship between molarityand percent mass units...how will you convert between moles and mass of solute? Howwill you convert between liters of solution and grams of solution?)
