    107.73KPa

    Explanation:

    Data obtained from the question include:

    T1 (initial temperature) = 300K

    P1 (initial pressure) = 101KPa

    T2 (final temperature) = 320K

    P2 (final pressure) = ?

    Using the the equation P1/T1 = P2/T2, the final pressure (i. e the new pressure) of the gas can be obtained as follow:

    P1/T1 = P2/T2

    101/300 = P2/320

    Cross multiply to express in linear form as shown below:

    300 x P2 = 101 x 320

    Divide both side by 300

    P2 = (101 x 320) / 300

    P2 = 107.73KPa

    Therefore, the new pressure of the oxygen gas is 107.73KPa
