Aspirin, C9 H8 O4 (molar mass 180.2g/mol), a drug used to relieve minor aches and pains, is prepared by the following reaction:
C7 H6 O3 (s) + C4 H6 O3 (l) --> C9 H8 O4 (s) + C2 H4 O2 (l)
If you need to prepare 45.0g of aspirin, and yield for the reaction is 85% how many grams of salicylic acid, C7 H6 O3 (molar mass 138.1g/mol) must you use?
i was wondering where to start? like I am really confused with that 85% thing too
