Question 3.9: CALCULATING A YIELD IN GRAMS, GIVEN A PERCENT YIELD Diethyl ...
CALCULATING A YIELD IN GRAMS, GIVEN A PERCENT YIELD
Diethyl ether (C_{4}H_{10}O), the “ether” used medically as an anesthetic, is prepared commercially by treatment of ethyl alcohol (C_{2}H_{6}O) with an acid. How many grams of diethyl ether would you obtain from 40.0 g of ethyl alcohol if the percent yield of the reaction is 87%?
\underset{Ethyl alcohol}{2 C_{2}H_{6}O(l)} \underrightarrow{Acid} \underset{Diethyl ether}{C_{4}H_{10}O(l)} + H_{2}O(l)STRATEGY
Treat this as a typical stoichiometry problem to find the amount of diethyl ether that can theoretically be formed from 40.0 g of ethyl alcohol, and then multiply the answer by 87% to find the amount actually formed.
