Mixture E consists of two esters X with two functions, Y with three functions in open circuit (MX < My). Complete combustion of mg of E yields 0.3 mol CO2 and 0.24 mol H2O. On the other hand, complete hydrolysis of milligram E with NaOH solution yields 3.48 grams of a mixture of two alcohols and a salt mixture of two carboxylic acids. Burning all two alcohols requires 0.1575mol 0 , yielding 0.12 mol CO2 . Find the percent by mass of Y in E.
