22) A student prepares aqueous sodium benzoate by adding 3.78 g of solid benzoic acid to 12 mL of 3 M aqueous NaOH solution. The student adds 6 M aqueous HCI to the solution until a precipitate is observed and the pH of the solution is acidic by pH paper. After cooling the mixture in ice for several minutes, the solid is recovered by vacuum filtration and allowed to dry. If 2.51 g of benzoic acid is obtained after drying, what is the percent recovery? a) 65.8 % b) 66.4 % c) 151 % d) 33.6 %

You have a 18 mL sample of acetylcholine (a neurotransmitter) with an unknown concentration and a pH of 8.35. You incubate this sample with the enzyme acetylcholinesterase to convert all of the acetylcholine to choline and acetic acid. The acetic acid dissociates to yield acetate and hydrogen ions. At the end of the incubation period, you measure the pH again and find that it has decreased to 6.03. Assuming there was no buffer in the assay mixture, determine the number of nanomoles of acetylcholine in the original 18 mL sample.
