    P (abs) = 48 KPa

    Explanation:

    Given that

    Vacuum gauge pressure = 44 KPa

    We know that Vacuum gauge pressure is also known as negative gauge pressure.

    P (gauge) = - 44 KPa

    Atmospheric pressure = 92 KPa

    P (atm) = 92 KPa

    We know that absolute pressure given as

    Absolute pressure = Atmospheric pressure + Gauge pressure

    Now by putting the values in the above equation

    P (abs) = 92 - 44 KPa

    P (abs) = 48 KPa

    Therefore the absolute pressure in the chamber will be 48 kPa
