The octanol - water aqueous buffer partition coefficients (P) for a drug used to treat glaucoma were obtained experimentally at various temperatures (T) and pH values. The results are presented in the following table: pH=6.25 pH=7.0 pH=7.25 T= 27 C 0.24 0.72 0.89 T= 30 C 0.31 0.84 1.06 T= 40 C 1.23 27.4 mg of this drug were dissolved in 100 mL of buffered water (pH=7.0; T=30) and then partitioned with octanol portions of 37.1 mL. Calculate how many mg of drug will remain in water after in the first extraction (Fill in ONLY numbers approximated to the 2nd decimal place) 1.49 Answer: 19.01
