How do you solve percent yield problems? Salicylic acid (FW = 138.12 g/mol), a reagent used to make aspirin, can itself be produced from oil of winter green (methyl salicylate, FW = 152.15 g/mol, d = 1.18 g/mol at 20 ºC), by reacting it with sodium hydroxide. This reaction is shown below. You measured out 7.14 mL of oil of wintergreen and 9.59 g of sodium hydroxide (FW = 39.997 g/mol). Experimentally, you produced 6.48 g of salicylic acid. What is your percent yield for this reaction?

C8H8O3 + NaOH → C7H6O3 + NaOCH3
