Solute X has a partition coefficient of 4.5 between water (phase 1) and chloroform (phase 2). The solute is initially dissolved in 50.0 mL. It is then extracted with 10.0 mL portions of chloroform. How many extractions must be performed for < 0.1% of X to remain in the water phase, i.e., > 99.9% of X has been transferred to the aqueous phase.
