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
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?
