A gas mixture containing 15mol%O2 is brought into contact with pure water at 293K in a well mixed contactor at atmospheric pressure. 50kmol/h of the gas mixture and 20.0kmol/h pure water are supplied. The exit gas and liquid streams leave the process in equilibrium. Assuming that only O2 is soluble in water, calculate the mole fraction of O2 at both outlet phases L1 and V1 (Henry's law for O2pA=4.01XA, where pA is in atm). (8 marks)
