Determine the mole fractions and partial pressures of CO2, CH4, and He in a sample of gas that contains 1.25 mole of CO2, 1.59 moles of CH4, and 3.41 moles of He, and in which the total pressure is 5.78 atm.
The mole fraction (x) of a component of a mixture is the number of moles of the component divided by the total number of moles in the mixture.
The total number of moles in the mixture is:
1.25 mol + 1.59 mol + 3.41 mol = 6.25 mol
Calculate the mole fraction of each component.
