Recall that Kow relates to the following equilibrium S (aq) S (org) where S is a substance which is partially soluble in both aqueous and organic phases. A certain POP (persistent organic pollutant) was stored as a 1.00 M solution in octanol. S has log Kw= 3.10. If a large spill of the POP occurred into a pond (pond and spill each have a volume of 15,500 L), what would be the total number of POP molecules in the aqueous phase of the pond? O9.31 x 1023 O4.08 1023 O8.62 x 1022 O741x 1024 1.13 x 1025
