Problem 2. Solid chemical A is dissolved in a liquid B to form an ideal solution. When a saturatedsolution is formed (i.e., no more solid can be dissolved), the mole fraction of A in this solution isfound to be xA = 0.1 at T = 300K.(a) Show that the mole fraction xA does not depend on any properties of the solvent B.(b) Calculate ΔGmelt0 for the material A.
