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.

A mixture of CO2 and Kr weighs 41.0 g and exerts a pressure of
0.729 atm in its container. Since Kr is expensive, you wish to
recover it from the mixture. After the CO2 is completely removed by
absorption with NaOH(s), the pressure in the container is 0.193
atm. (a) How many grams of CO2 were originally present? (b) How
many grams of Kr can you recover?
