Ethyl butyrate CH_2CH_2CH_2CO_2CH_2CH_3, is an artificial fruit flavor commonly used in the food industry for such flavors as orange and pineapple. Its fragrance and taste are often associated with fresh orange juice, and thus it is most commonly used as orange flavoring. It can be produced by the reaction of butanoic acid with ethanol in the presence of an acid catalyst (H^+): CH_3CH_2CH_2CO_2H(l) + CH_2CH_2OH(l) rightarrow^H^+ CH_3CH_2CH_2CO_2CH_2CH_3(l) + H_2O(l) Given 8.55 g of butanoic acid and excess ethanol, how many grams of ethyl butyrate would be synthesized, assuming a complete 100% yield? Express your answer in grams to three significant figures. A chemist ran the reacts and obtained 5.40 g of ethyl butyrate. What was the percent yield? Express your answer as a percent to three significant figure.
