    Answer: 19kpa

    Explanation:

    The total pressure of a mixture of gases is the sum of the partial pressure exacted by the individual gases.

    P total = P X + P Y

    From the question above:

    P total = P. nitrogen + P. oxygen

    123.5kpa = 104.5kpa + P. Oxygen

    P. Oxygen = 123.5kpa - 104.5kpa

    = 19kpa
