A closed container has a mixture of methane, CH4, ethane C2H6, and propane C3H8. If 12.5 g of methane, 36.0 g of ethane, and 14.0 g of propane have a total pressure of 890. mm Hg, what is the partial pressure of each of the gases in the container?

  • chemistry - ,

    Convert grams each gas to mols.
    mols = g/molar mass

    Convert each gas to mole fraction.
    Xeach gas = mol each gas/total mols.

    partial pressure each gas = Xeach gas*Ptotal
