Homework Statement



A chemical reaction takes place in a container of cross-sectional area 100 cm2. The container has a loosely fitting piston at one end. As a result of the reaction, then piston is pushed out by 10 cm against an external pressure of 101.3 kPa. Calculate the work of expansion done by the system.

I really dont know what equation to be using?
