    Answer:

    4202.1 K

    Explanation:

    From;

    PV=nRT

    P= pressure of the gas = 18.5 bar

    V = volume of the gas = 115L

    n= number of moles of the gas =  6.1 mole

    T= temperature of the gas = ?

    R = gas constant = 0.083 L⋅bar⋅K−1⋅mol−1

    T = PV/nR

    T = 18.5 * 115/6.1 * 0.083

    T = 2127.5/0.5063

    T= 4202.1 K
