    -2.79 x 10²J

    Explanation:

    using the pressure volume work formula which states that

    work = - PΔV

    = - (1.0 atm) (2.7-0.0) L = - 2.7L. atm

    Convert litre. atmosphere to Joules.

    1 L. atm = 101.325 joules

    -2.75 L. atm = - 2.75 x 101.325 = - 278.64375 =

    Work = - 2.79 x 10²J
