Phenol is approximately 12 times more soluble in 1 volume of isopropyl ether than it is in 1 volume of water. How many extractions are required to decrease the concentration of phenol below 100 mg/L in a wastewater containing 2000 mg/L of phenol if an ether-to-watewater ratio of 0.2 by volume is used in each extraction?

Remember:

Kd = Ci, org. solvent / Ci, water = (molesi, org. solvent/Vorg. solvent) / (molesi, water/Vwater)
