Whatisthe total pressure of the mixture of gases in the tank?The total pressure is the sum of the partial pressures:•PTOTAL=PHe+Po,=9.3 atm+2.4 atm=11.7 atmAt this point we need to define themole fraction:the ratio of the number of molesof a given component in a mixture to the total number of moles in the mixture.The Greeklowercase letter chi(X)is used to symbolize the mole fraction. For example, for a givencomponent in a mixture, the mole fractionXlisSeparatingGasesAssumeyou work for an oil companythatowns a huge natural gas reservoir containinga mixture of methane and nitrogen gases. In fact, the gasmixture containsso much nitrogen that it is unusable as afuel. Your jobis to separatethe nitrogen(N2) fromthemethane (CH4).How might you accomplishthis task? Youclearly need some sort of "molecular filter" that will stop theslightly larger methane molecules (size=430 pm) and allowthe nitrogen molecules(size=410 pm) to pass through.
