The partial pressure of CH4(g) is 0.175 atm, and the partial pressure of O2(g) is 0.250 atm in a mixture of the two gases. The mixture occupies a volume of 10.5 L at 65 oC. Solve all three parts of the question. 1) The mole fraction of CH4(g) is , and the mole fraction of O2(g) is . 2) The total number of moles of gas in the mixture is . 3) There are grams of CH4(g) and grams of O2(g) in the mixture.

1)

2)

3)

Explanation:

Hello,

1) In this case, given the partial pressures of both methane and oxygen we can compute the mole fraction by considering each partial pressure as shown below:

2) Now, we use the ideal gas equation to compute the total mass with the total pressure:

3) Finally, by using the mole fractions, total moles and molar masses we compute the grams of both methane and oxygen:
