The process in which an organic acidand an alcohol react to form an ester and water is knownas esterification. Ethyl butanoate ( C 3 H 7 COO C 2 H 5 ), anester, is formed when the alcohol ethanol ( C 2 H 5 OH)and butanoic acid ( C 3 H 7 COOH) and are heated in thepresence of sulfuric acid.C 2 H 5 OH(l) + C 3 H 7 COOH(l) →C 3 H 7 COO C 2 H 5 (l) + H2  O(l) Determine the mass of ethyl butanoate produced if4.50 mol of ethanol is used.
