Chapter 8.4, Problem 8PPA

Diethyl ether is produced from ethanol according to the following equation:

$2{\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{OH(}l\text{) }\to {\text{ CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{OCH}}_2{\text{CH}}_3(l)+{\text{H}}_2\text{O(}l\text{)}$

Calculate the percent yield if 68.6 g of ethanol react to produce 16.1 g of ether.
