If you have 6.76 g of caffeine dissolved in 57.2 mL of water and the extraction coefficient between H2O and CH2Cl2 is 21.51. How many grams of caffeine will extract into the CH2Cl2 layer if you use 89.9 mL?

Question

If you have 6.76 g of caffeine dissolved in 57.2 mL of water and the extraction coefficient between H2O and CH2Cl2 is 21.51. How many grams of caffeine will extract into the CH2Cl2 layer if you use 89.9 mL?

Step 1

Extraction is a technique by which a compound dissolved in a solvent is extracted into another solvent by partitioning between the two solvents.

The strength of extraction is known as the extraction efficiency and represented by extraction coefficient.

Step 2

Given here an extraction of caffeine dissolved in water into CH2Cl2 (organic solvent).

Extraction coefficient = Caffeine in CH2Cl2/caffeine in water = 21.51

let X amount of caffeine is extracted in CH2Cl2

starting mass of caffeine in water = 6.76 g
