    Answer:

    15.37 atm

    Explanation:

    According to Dalton’s law of partial pressure, the total pressure of a mixture of gases in the tank is a sum of the individual pressures of all the gases. Hence;

    PT = P1 + P2 + P3 ———–

    So;

    Ptotal = Phelium + Poxygen

    Poxygen = 4.63 atm

    Ptotal = 20.0 atm

    Phelium = 20.0 atm – 4.63 atm

    Phelium = 15.37 atm
