Answer to Question #85168 in General Chemistry for C

Question

In the experiment, 2.00 g of salicylic acid (molar mass = 138.1 g/mol) reacts with an excess amount of acetic anhydride

a. Calculate the theoretical yield of acetylsalicylic acid (molar mass = 180.2 g/mol) for this synthesis.

b. After completing the Experimental Procedure, a mass of 1.78 g of acetylsalicylic acid was recovered. What is the experimental yield for its synthesis? Express the yield with the correct number of significant figures.

2. Recrystallizing the aspirin removes some (or all) of the impurities in the sample. Explain how the recrystallization process performs this function.
