    876.63 mmHg

    Explanation:

    Step 1:

    Data obtained from the question:

    Initial volume (V1) = 5.3 L

    Initial pressure (P1) = 735 mmHg

    Initial temperature (T1) = 28°C

    Final volume (V2) = constant i. e the same as the initial volume (5.3L)

    Final temperature (T2) = 86°C

    Final pressure (P2) = ... ?

    Step 2:

    Conversion of celsius temperature to Kelvin temperature. This is illustrated below:

    Temperature (Kelvin) = temperature (celsius) + 273

    Initial temperature (T1) = 28°C

    Initial temperature (T1) = 28°C + 273 = 301K

    Final temperature (T2) = 86°C

    Final temperature (T2) = 86°C + 273 = 359K

    Step 3:

    Determination of the new pressure of the gas. This is illustrated below:

    Since the volume of the gas is constant, the new pressure of the gas can be obtained by the equation below:

    P1/T1 = P2/T2

    Initial pressure (P1) = 735 mmHg

    Initial temperature (T1) = 301K

    Final temperature (T2) = 359K

    Final pressure (P2) = ... ?

    P1/T1 = P2/T2

    735/301 = P2/359

    Cross multiply to express in linear form

    301 x P2 = 735 x 359

    Divide both side by 301

    P2 = (735 x 359) / 301

    P2 = 876.63 mmHg

    Therefore, the new pressure of the gas is 876.63 mmHg
