    Answer:

    191.4K

    Explanation:

    Using the ideal gas law equation as follows:

    PV = nRT

    Where;

    P = pressure (atm)

    V = volume (L)

    n = number of moles (mol)

    R = gas law constant (0.0821 Latm/molK)

    T = temperature (K)

    According to the information provided in this question:

    n = 4.2moles

    P = 5.5atm

    V = 12.0 L

    T = ?

    Using PV = nRT

    5.5 × 12 = 4.2 × 0.0821 × T

    66 = 0.345 T

    T = 66/0.345

    T = 191.4K
