Question

Please solve part B and C

It can be produced by the reaction of butanoic acid with ethanol in the presence of an acid catalyst (H Part A Given 8.45 g of butanoic acid and excess ethanol, how many grams of ethyl but rate would be synthesized, assuming a complete 100% yield? Express your answer in grams to three significant figures. Hints mass of ethyl butyrate = Submit 11.1 g My Answers Give Up Correct The mass of product produced assuming a 100% yield is called the theoretical yield. Part B A chemist ran the reaction and obtained 5.70 g of ethyl butyrate. What was the percent yield? Express your answer as a percent to three significant figures. Hints percent yield = 6 1 .7 Submit My Answers Give Up Incorrect; Try Again Part C The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0% yield. How many grams would be produced from 8.45 g of butanoic acid and excess ethanol? Express your answer in grams to three significant figures. Hints

Explanation / Answer

(B)
Given actual yield = 5.70 g.

Theoretical yield = 11.1 g. ( From A)

% Yield = Actual yield * 100 / Theoretical yield = 5.70 * 100 / 11.1 = 51.4 %

(C)

If 100 % yield gives 11.1 g. of product.

Then for 78.0 % of yield,

Mass of product = 11.1 * 78.0 / 100 = 8.66 g.
