A gas experiences isobaric expansion at 2.0 atm from 4.2 m3 to 7.5 m3 . How much work was done by the gas on the environment?

A room in a spaceship experiences catastrophic failure and loses its atmosphere to space. The room, which is 8m x 8m x 8m, contained 54682 mols of air at standard temperature and pressure. How much work does the atmosphere do if the venting of atmosphere is adiabatic and the final temperature of the gas is 8.21 K?
