The composition by mass of methyl alcohol ethyl alcohol, Ask an Expert

Academics

The composition by mass % of methyl alcohol, ethyl alcohol, n-Propyl alcohol and water in two solutions A and B are given below.

Methyl alcohol Ethyl alcohol Propyl alcohol Water
Solution A (20°C) 2 20 15 63
Solution B (20°C) 5 75 5 15

(a) What are the masses in kg of solution A and solution B required, to make 100 kg of a mixture containing 25% ethyl alcohol by mass?

(b) Assume that the volume of the mixture equals the sum of the pure components volumes. Also assume that all alcohol and water are completely miscible. Calculate the densities (kg/m3) of solutions A and B and the mixture containing 25% ethyl alcohol by mass?
