An industrial chemist synthesises ethyl ethanoate via the esterification of ethanol and ethanoic acid.
Based on the mass of the limiting reactant, the theoretical maximum yield of ethyl ethanoate is 12.5 g.
After purification and distillation, the actual mass of ethyl ethanoate obtained is 9.15 g.
Calculate the percentage yield of ethyl ethanoate. Give your answer to 3 significant figures.
