Hello, this is a simple dilution problem: C1V1=C2V2, where C=concentration & V=volume   Fill in the blanks:   C1V1=C2V2   (0.188 M)(25.0 uL)=C2(150X10^3 uL)   After converting 150.0 mL to uL, solve for C2 algebraically.   C2=3...

Helllo Brook, I expect that "logKOW" means the log of the octanol-water partition coefficient.  Taking the inverse log of 3.12, we get 1318.256739.  If before the extraction we have 0.10g of o-xylene in water, then post extraction we have x grams of o-xylene in octanol, and...
