The active ingredient in aspirin is acetylsalicylic acid, which has the chemical formula . An aspirin pill contains 300 mg of acetylsalicylic acid. How many moles of acetylsalicylic acid does it contain?

Create balanced chemical reactions for the following reactions. Organic reactions should be written with the line-angle drawing of each structure. 1. Reacting salicylic acid with acetic anhydride to form acetylsalicylic acid, with the use of sulfuric acid as a catalyst. 2. Water reacting with acetic anhydride to form acetic acid.

The molecular formula of acetylsalicylic acid (aspirin), one of the most commonly used pain relievers, is C 9 H 8 O 4. a. Calculate the molar mass of aspirin. b. A typical aspirin tablet contains 500. mg C 9 H 8 O 4. What amount (moles) of C 9 H 8 O 4 molecules and what number of molecules of acetylsalicylic acid are in a 500.-mg tablet?

the synthesis of aspirin we react salicylic acid with acetic anhydride. The balanced chemical equation is: 2HOOCC6H4OH + C4H6O3 → 2HOOCC6H4O2C2H3 + H2O salicylic acid acetic anhydride acetyl salicylic acid water If we mix together 27.9 grams of salicylic acid with 14.4 grams of acetic anhydride in this reaction, we obtain 30.7 grams of aspirin.
