You have a sample of 90 mL cola drink that contains 50 mg of dissolved caffeine. Calculate the total mass of caffeine extracted using 54 mL of dichloromethane in each of the following procedures: the entire volume of dichloromethane is used in one step; the dichloromethane is divided into two (27 mL) portions in a two-step extraction and into three (18 mL) portions in a three-step extraction. Please use two decimal places.

You are attempting to purify a compound via recrystallization. You prepare the process through the following method: 1) Dissolve the material in a minimal amount of hot EtOH. 2) Slowly add hot water until the compound is slightly cloudy. 3) Add a small amount of EtOH until the solution is just clear (still hot). 4) Cool to RT. Upon cooling to RT you notice that the compound is not precipitating out of solution. You decide to boil off some ethanol. Upon completing this step and cooling to RT you notice that the compound is precipitating out as desired! In which solvent is your compound the least soluble? Ethanol O Water O The ethanol water mixture Insoluble in all of these solvents
