    Answer:

    4.7 atm

    Explanation:

    From the question given above, the following data were obtained:

    Total pressure (P) = 15.3 atm

    Pressure of Helium, P(He) = 3.2 atm

    Pressure of Oxygen, P(O) = 7.4 atm

    Pressure of Argon, P(Ar) =?

    The pressure of Argon, P(Ar) in the tank can be obtained as illustrated below:

    P = P(He) + P(O) + P(Ar)

    15.3 = 3.2 + 7.4 + P(Ar)

    15.3 = 10.6 + P(Ar)

    Collect like terms

    15.3 – 10.6 = P(Ar)

    4.7 = P(Ar)

    P(Ar) = 4.7 atm

    Therefore, the pressure of Argon, P(Ar) in the tank is 4.7 atm
