A 7,030 kg-mole ethyl acetate aqueous solution containing 85-mole % (mol %) water is added to a 69-w % ethyl acetate aqueous solution to obtain 52-w % ethyl acetate aqueous solution. Find the mean molecular weight of the 7,030 kg-mole ethyl acetate aqueous solution. Calculate the amounts (kg) of the 69-w % ethyl acetate aqueous solution and the 52-w % ethyl acetate aqueous solution using the Chemical Engineering Handbook
