The partition coefficient of a base B (monoacidic) at a particular pH, in an octanol-water mixture

is 1.45. Consider an experiment where 3.5 g of B are shaken with 100 mL of octanol and 50 mL

of water.

Molar mass of B = 101.19 g mol-1

(i) Calculate the mass of B in the aqueous layer after shaking.
