Extraction of caffeine:

You had extracted 2 g of crude caffeine and you were in a hurry. Instead of doing the 6 successive extractions with 2ml portions of methylene chloride, you only did 2 successive extractions with 6 ml portions of solvent. Now, calculate the total mass of pure caffeine recovered in these 2 operations.
