1. A 0.421g sample of aspirin prepared in the laboratoryis dissolved in 95% ethanol, diluted with water, and titrated tothe phenolphthalein endpoint with 17.3mL of 0.114 M NaOH.
a. How many moles of acetylsalicylic acid (molar mass=180.0g/mol) are present in teh sample?
b. Caculate the percent purity of acetylasalicylic acid in theasprin sample.
c. In the experiment 2.00 g of salicylic acid (molar mass =138.1 g/mol) reacts with an excess amount of acetic anhydride.Calculate the theoretical yield of acetylsalicylic acid ( molarmass = 180.0 g/mol) for this synthesis
d. Determine the number of grams of acetylasalicyclic acidthat will react with 20.0 mL of 0.100 M NaOH.
