One litre of aqueous sample containing the organic pollutant, polychlorinated biphenyl (PCB), was brought to a lab for analysis. Two extractions each with 50 ml of fresh organic solvent were performed. On analysis of the aqueous phase after the first extraction, the concentration of PCB was 10 µg/ml. After the second extraction with fresh organic solvent, the concentration of PCB in the aqueous phase was 0.6 µg/ml. Determine the distribution ratio of PCB under these conditions
