A mixture contains two compounds, X and Y. Both compounds X, Y have a solubility =1 g/100 mL of solvent at the temperature of 20 degree Celsius and 16 g/ 100 mL of solvent at 100 degree Celsius. The sample is composed of 3.5 grams of X and 10 grams of Y. At 100 degree Celsius the entire sample just dissolves in a minimum amount of solvent. The solution is cooled to twenty degree Celsius and crystals are collected. Compute the composition of the crystals and the yield of the process. Also determine the composition of the mother liquor?
