1.The total pressure of a mixture of O2(g) and H2(g) is 1.95 atm. The mixture is ignited and the resulting water is removed. The remaining mixture is pure H2(g) and exerts a pressure of 0.210atm when measured at the same temperature and volume as the original mixture. What were the mole fractions of O2(g) and H2(g) in the original mixture?

A mixture of H2(g) and O2 (g) at 1.50 atm in a rigid container at temperature T is ignited. The remaining gas, which is entirely H2 (g) exerts a pressure of 0.30 atm at tempertaure T. Assume that the gases are ideal and the H2O(l) formed in the combustion reaction takes up negligible volue in the container. Determine the mole fraction of O2(g) in the original mixture.

A mixture of CH4 (g) and C2H6 (g) has a total pressure of 0.53 atm. Just enough O2 was added to the mixture to bring about it's complete combustion to CO2 (g) and H2O (g). The total pressure of the two product gases is found to be 2.2 atm. Assuming constant volume and temperature, find the mole fraction of CH4 in the original mixture.
