A common concept that crops up in a Dalton's Law context is mole fraction. Suppose you had equal moles of two different gases in a mixture. Then the mole fraction for each would be 0.50. The mole fraction for each gas is simply the moles of that gas divided by the total moles in the mixture. Seems simple enough. How does it relate to Dalton's Law? Answer: the mole fraction also gives the fraction of the total pressue each gas...

A mixture of methane gas, CH4(g), and pentane gas, C5H12(g), has a pressure of 0.5015 atm when placed in a sealed container. The complete combustion of the mixture to carbon dioxide gas, CO2(g), and water vapor, H2O(g), was achieved by adding exactly enough oxygen gas, O2(g), to the container. The pressure of the product mixture in the sealed container is 2.421 atm. Calculate the mole fraction of methane in the initial mixture assuming the temperature and volume remain constant. Xch4=
