Question

1 You are given a mixture containing two compounds A and B Both compounds have a solubility of 1 00 g 100 mL of solvent at 20 C and 12 0 g 100 mL of solvent at 100 C The sample is composed of 1 60 g of A and 9 90 g of B At 100 C all of the sample just dissolves in a minimum amount of solvent The solution is then cooled to 20 C and the crystals are collected a What is the composition of the crystals B b What is the percent yield of the process Yield c What is the composition of the mother liquor A B 2 If the mixture described in question 1 are recrystallized from 100 mL of solvent instead of the minimum amount a What is the composition of the crystals
