    Answer:

    969.6 kPa

    Explanation:

    Applying,

    P/T = P’/T’………………… Equation 1

    Where P = Initial pressure of the gas, T = Initial temperature of the gas, P’ = Final pressure of the gas, T’ = Final temperature of the gas

    make P’ the subject of the equation

    P’ = PT’/T…………….. Equation 2

    From the question,

    Given: P = 121.2 kPa, T’ = 2111°C = (273+2111) = 2384 K, T = 25°C = (273+25) K = 298 K

    Substitute these values into equation 2

    P’ = (121.2×2384)298

    P’ = 969.6 kPa
