A student dissolved 3.72 g of sodium p-nitrobenzoate (MW 189.10 g/mol) in 20 mL H,0. The solution was then acidified to a pH of 1 using 10% HCI after which a crystalline precipitate of p-nitrobenzoic acid was obtained. The reaction is given below: H-CI HO, Na* N+ sodium p-nitrobenzoate p-nitrobenzoic acid The p-nitrobenzoic acid (MW 167.12 g/mol) was collected by vacuum fitration and was found to weigh 2.60 g. Determine the percent yield for this reaction.
