please answer clearly 1 (Lecture LOI) 50 m3 of a 35-C gas mixture with composition 98 miole percent air(3), 2 mole percent toluene(1) is contacted with 400 kg of 35°C pure n-decane(2). The vapor-liquid system is allowed to come to equilibrium isothermally at 35 oC at a constant pressure of 1.0 atm. What are the final compositions of the liquid and vapor phases? You should neglect dissolution of air in the liquid, but you must account for evaporation of n-decane....
