1.-Determine the mole fractions and partial pressures ofCO2, Ch4 and He in a sample of gas thatcontains 0.250 mole of CO2, 1.29 moles of CH4, and 3.51 moles of He, and in which the totalpressure is 5.78 atm.
2.- Determine the partial pressure and number of moles of eachgas in a 15.75 L vessel at 30.0 oC containing a mixtureof xenon and neon gases only. The total pressure in the vessel is6.50 atm, and the mole fraction of xenon is0.761.
