how to you calculate the partition coefficient of benzoic acid .13 grams in a 1.6 mL CH2Cl2 and 1.6 mL water?

1 answer

Ko/aq = (concn org layer)/(concn aq layer)
o is organic layer.
aq is aqueous layer.
I can't tell from your post if that is 0.13 g in 1.6 mL organic layer or if that is a period after benzoic acid. You need the concn in EACH layer and you list g only in the organic layer and nothing for the aq layer.
