2. To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. A chemical engineer places a mixture of noble gases consisting of 5.50 g of He and 35.0 g of Kr in a piston cylinder assembly at STP. (a) "Calculate the mole fraction of Kr gas. (b) Calculate the partial pressure of Kr gas. Parameter Molar mass (g/mole) Не 4.0 Kr 83.8
