a.) Given 7.75 g of butanoic acid and excess ethanol, how many grams of ethyl butyrate would be synthesized, assuming a complete 100 % yield?
b.) A chemist ran the reaction and obtained 5.35 g of ethyl butyrate. What was the percent yield?
c.) The chemist discovers a more efficient catalysts that can produce ethyl butyrate with a 78 \% yield. How many grams would be produced from 7.75 g of butanoic acid and excess ethanol?
