    Answer: 5.3 moles

    Explanation:

    Hi, to answer this question we have to apply the next formula:

    n = PV/RT

    Where:

    n = number of moles

    P = Pressure = 2.15 atm

    V = volume = 60.5 L

    R = 0.0821 atm (L) / mol (K)

    T = temperature = 25 ° + 273.15 = 298.15 Kelvin

    Replacing with the values given:

    n = 2.15 (60.5) / 0.0821 (298.15) = 5.3 moles.

    Feel free to ask for more if needed or if you did not understand something.
