A student monitors the synthesis of ethyl ethanoate (Mr=88.0M_r = 88.0Mr=88.0) by reacting 0.250 mol of ethanoic acid (Mr=60.0M_r = 60.0Mr=60.0) with an excess of ethanol.
CH3COOH+C2H5OH⇌CH3COOC2H5+H2O \text{CH}_3\text{COOH} + \text{C}_2\text{H}_5\text{OH} \rightleftharpoons \text{CH}_3\text{COOC}_2\text{H}_5 + \text{H}_2\text{O} CH3COOH+C2H5OH⇌CH3COOC2H5+H2OAfter purification, the student isolates 15.4 g of ethyl ethanoate.
