22. The molar mass of a solid carboxylic acid is determined by titrating a known mass of the acid with a standardized solution of NaOH to a phenolphthalein endpoint. Which errors will lead to a molar mass that is smaller than the actual molar mass? I. Some of the acid is spilled when being transferred into the titration flask. II. The endpoint is recorded when the solution is dark red in color rather than light pink. a. T only b. Il only c. Both I and II d. Neither I nor II
