A36.0 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. separation and analysis of the aqueous phase shows that it now contains 12.0 mg of the organic compound. calculate the partition coefficient for the compound between hexane and water (kphexane/water). your answer should reflect the proper number of significant figures.

Explanation:

Hello,

In this case, considering the involved substances, after the extraction we will have two phases, an organic which is rich in hexane and an aqueous which is rich in water. In this manner, the given definition of the partition coefficient involves the calculation of the sample's concentration in both solvents, it means water and hexane as shown below:

Now, the partition coefficient turns out being:
