    Answer:pressure of the krypton = 350torr, Total pressure = 560torr

    Explanation:

    Note:The partial pressure of an individual gas = to the total pressure multiplied by the mole fraction of that gas.

    Given

    Argon=3moles

    pressure for Argon = PAr = 210 torr

    Krpton = 5, Kr pressure = ?

    a) PArgon = mole fraction of Argon x total pressure

    3/3+5 x total pressure = 210

    total pressure = 210x 8/3

    Total pressure = 560torr

    b) pressure for Krypton = Krypton mole fraction x total pressure

    5/8 X 560

    = 350torr

    pressure of the krypton = 350torr
