CH_{3}COOH + HOCH_{2}CH_{3} CH_{3}COOCH_{2}CH_{3} + H_{2}O Based on the equation above, what mass of acetic acid (CH_{3}COOH) is needed to prepare 267.16 g of ethyl acetate (CH_{3}COOCH_{2}CH_{3}) if the percent yield of the reaction is 92.7%? (Assume ethanol is present in excess, ethyl acetate = 88.676 g/mol, and acetic acid = 60.0536 g/mol.)
