5) A solid substance D is soluble in ethanol to the extent of 3.20 mg/1.00 ml. of ethanol at 25 °C and 16.0 mg/1.00 mL of ethanol at 78 °C. You have been provided with a sample that contains 60.0 mg of D and 16.0 mg of an impurity E By showing all the calculation steps, describe how you would be able to purify D if E has the same solubility behavior as D in ethanol, Indicate the number of crystallization steps required to purify D, as well as the amount and percent recovery of pure D obtained after the crystallization steps have been completed. Show all calculations. (Assume that there are no insoluble impuities present in the sample). BE CLEAR AND SHOW ALL THE STEPS OF THE CALCULATIONS.
