. At 25 C, the aqueous solubility of TCE in water is xTCE=2x10-4 on the mole fraction scale. At 25 C, the infinite dilution activity coefficient for TCE in octanol is 4. Determine the octanol/water partitioning coefficient (Kow) for TCE at 25 C. The molar volume of water is 18 cm3 /mol and the molar volume of octanol is 157 cm3 /mol. Kow = Coctanol Cwater where C is in units of concentration (e.g., mg/L or mol/L)
