Question 1: In an example of the aspirin
reaction, 2.07 g salicylic acid was
reacted with 4.2 mL acetic anhydride
(density 1.075 g/mL), in the presence of a few
drops of 18 M H2SO4 as catalyst. (show
step by step working)
a) Calculate the number of
moles of salicylic acid if 2.07 g was used. Give your answer
to 3 sig fig.
b) Calculate the number of
moles of acetic anhydride if 4.5 g was used (mass = vol x density).
Give your answer to 2 sig fig.
c) Which is the
limiting reactant in this experiment? (salicylic acid or acetic
anhydride?)
d) What is the theoretical
yield of aspirin from this reaction? Give your answer to 3
sig fig.
