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.

This question has been solved!
Explore an expertly crafted, step-by-step solution for a thorough understanding of key concepts.
Step 1: Single-step extraction uses all 54 ml of dichloromethane, extracting half the caffeine (25 mg).
VIEWStep 2: In two steps, 27 mL of dichloromethane each extracts half of the caffeine, totaling 100 mg.
VIEWStep 3: In three steps, 20 mL of dichloromethane each extracts one-third of the caffeine, totaling 50 mg.
