    The mole fraction of SF6 = 0.505

    Explanation:

    Step 1: Data given

    A gas mixture has partial pressure of:

    120 torr N2

    350 torr Ar

    480 torr SF6

    Step 2: Calculate the total pressure

    Total pressure = P (N2) + P (Ar) + P (SF6)

    Total pressure = 120 + 350 + 480 = 950 torr

    Step 3: Calculate the mole fraction

    Mole fraction = Partial pressure / total pressure

    Mole fraction SF6 = 480 torr / 950 torr

    Mole fraction SF6 = 0.505

    The mole fraction of SF6 = 0.505
