Final answer:
To calculate the percent yield, convert the mass of ethanol to moles, use stoichiometry to determine the moles of ether, convert moles of ether to grams, and divide actual grams by theoretical mass. The percent yield is 87.6%.
Step-by-step explanation:
To calculate the percent yield, we need to compare the actual amount of ether produced to the theoretical amount of ether that should have been produced based on the balanced equation.
First, convert the mass of ethanol to moles of ethanol using its molar mass (46.07 g/mol).
Next, use the stoichiometry of the balanced equation to determine the moles of ether that should have been produced.
Finally, convert the moles of ether to grams and divide the actual grams of ether by the theoretical mass to determine the percent yield. In this case, the percent yield is 87.6%.
