Final answer:
The estimated percent yield of a reaction producing 13.0 g of ethyl acetate from 10.0 g of CH3CO2H is 86.1%, which is closest to the provided option c) 85%.
Step-by-step explanation:
The percent yield of a reaction is calculated by taking the actual yield (the amount of product actually obtained from the reaction) and dividing it by the theoretical yield (the amount of product that should be obtained if all reactants were converted to products, based on stoichiometry), then multiplying by 100 to get a percentage.
In this case, we are given that the actual yield of ethyl acetate is 13.0 g, and we are provided with the information that 15.1 g of ethyl acetate can be theoretically prepared from the reaction given the starting materials. Hence, the percent yield is calculated as follows:
Percent Yield = (Actual Yield / Theoretical Yield) × 100
Percent Yield = (13.0 g / 15.1 g) × 100
Percent Yield = 86.1% which is not exactly matching any of the provided options (a-d), but it is closest to option c) 85%
