An unknown substance “A" was allowed to partition between a mixture of 150 mL water and 80 mL benzene. After titration, you found that 0.75 moles of “A" was dissolved in the water while 0.60 moles dissolved in benzene. Calculate for the partition coefficient of substance “A". What can you infer about the nature of substance “A" based on the value of the partition coefficient?
