Q3 (3points) A mixture is 10.0 mole % ethyl alcohol, 75.0 mole % ethyl acetate (C4H8O2), and 15.0 mole % acetic acid. Calculate the mass fractions of each compound. What is the average molecular weight of the mixture? What would be the mass (kg) of a sample containing 25.0 kmol of ethyl acetate? Ethyl acetate: C4H8O2; Ethyl alcohol: C2H6O; Acetic acid: C2H402
