A 78 mg sample of an organic compound (molar mass = 84.0 g/mol) is partitioned between 2.00 mL of water and 2.00 mL of methylene chloride. Separation and processing of the organic phase results in the isolation of 58 mg of the organic compound. Calculate the partition coefficient for the compound between methylene chloride and water (Kpmethylene chloride/water). Your answer should reflect the proper number of significant figures.
A 36.0 mg sample of an organic compound (molar mass = 84.0 g/mol) is dissolved in 10.0 mL of water. This aqueous solution is extracted with 5.0 mL of hexane.

1. It can be shown mathematically that 2 or more smaller extractions (using smaller portions of asolvent) are better than 1 single extraction using a larger portion of solvent. Suppose a particularextraction proceeds with a partition coefficient, Ksp, of 10. Ksp = C2/C1 where C2/C1 is the distribution of a compound between diethyl ether (C2) andwater (C1) in grams/L. Use grams/L in your calculations. 5.00 g of an organic compound is dissolved in 100 ml of water. Show that two successive 50.0 mlextractions with diethyl ether will yield more compound than one 100 ml extraction.
The partition coefficient for caffeine between dichloromethane and water is 4.6. Assume that a 100 mL tea solution (in water) contained 100 mg of caffeine. What is the theoretical yield of caffeine in the methylene chloride if you extract with one 100 mL portion of methylene chloride?
As part of a lab exercise, your group was assigned an unknown compound X for which you had to determine its partition coefficient between an organic solvent and water.
