    Answer: The partial pressure of N_{2}O is 0.35 atm.

    Explanation:

    Given: Total pressure = 0.98 atm

    Partial pressure of O_{2} = 0.48 atm

    Partial pressure of Ar = 0.15 atm

    Partial pressure of N_{2}O = ?

    Total pressure is the sum of partial pressure of each component present in a mixture of gases.

    Hence, partial pressure of N_{2}O is calculated as follows.

    Total pressure = P_{N_{2}O} + P_{O_{2}} + P_{Ar}

    Substitute the values into above formula as follows.

    Total pressure = P_{N_{2}O} + P_{O_{2}} + P_{Ar}\\0.98 atm = P_{N_{2}O} + 0.48 atm + 0.15 atm\\P_{N_{2}O} = 0.35 atm

    Thus, we can conclude that the partial pressure of N_{2}O is 0.35 atm.
