chemistry help please?

A gas mixture with a total pressure of 5.0 atm is used in a hospital. If the mixture contains 5.9 moles of nitrogen and 1.3 moles of oxygen, what is the partial pressure, in atmospheres, of each gas in the sample?

    Calculate the mole fraction of one gas:

    X N2 = 5.9 mol / (5.9 + 1.3 mol) = 0.819

    Partial pressure N2 = 0.819 X 5.0 atm = 4.1 atm

    Partial pressure O2 = 5.0 - 4.1 = 0.9 atm
