The mixture is not stable and forms two liquid phases. One of the phases as a composition of 28% component 1, while other phase has a composition of 98% of component 1.

Consider the figure that provides the molar Gibbs free energy of mixing as a function of composition for a binary mixture.
If the overall composition of the mixture is 20% of component 1, is the mixture stable? If not, what are estimates of the compositions of the liquid phases that are in equilibrium?
