3) A mixture of 70wt% water, 20% methyl isobutyl ketone acetone and the remainder acetone are brought to equilibrium at 25C. If the total mass of the system is 2.8kg, use the data in triangular phase diagrams for water-acetone-methyl isobutyl ketone to estimate the composition and mass of each phase of the mixture. 3) A mixture of 70wt% water, 20% methyl isobutyl ketone acetone and the remainder acetone are brought to equilibrium at 25C.
