The distribution coefficient of styrene distributed between ethylbenzene and ethylene glycol at 25 degrees C is .19 mass fraction in the ethylene glycol phase per mass fraction in the ethylbenzene phase. One hundred grams of pure ethylene glycol is added to 120g of a mixture containing 75wt% ethylbenzene and 25% styrene and the resulting blend is allowed to equilibrate. How much styrene transfers to the ethylene glycol phase, assuming that ethylene gylcol and ethylbenzene are immiscible?
