Acetyisalicylic acid commonly knowWn as Aspirin is used tó treat feve inflammation, and acts as a blood thinning agent. A group of STEM student experimented on the synthesis of this compound using recrystallizatio technique. The following are the initial materials for the experiment: 5.00 g c pure salicylic acid, 7.14 g of acetic anhydride and 8 drops concentrate sulfuric acid as catalyst. After successful synthesis, the group was able to collec 5.25 grams of Aspirin. (Atomic weights: Ċ= 12 amu; H = i amu; O= 16 amu density acetic anhydride = 1.08 g/mL) Chemical reaction involved: он E-CH, с-он C-CH CH3-C-OH -O- Acetic anhydride Acetic Acid Salicylic acid (C7H&O3) Acetylsaicyic acid (C 9H3O4) (C 4H6O3) (C 2 H402) ow many molecules will be present in the Aspirin produced?
