A sample of gas occupies a volume of 63.1 mL. As it expands, it does 130.4 J of work on its surroundings at a constant pressure of 783 torr. What is the final volume of the gas?

I know that P= 1.03 ATM when converted. I think I'm supposed to use the equation w= -PdeltaV and solve for deltaV? Then add the initial volume to deltaV to get the final volume? Please explain, I'd really appreciate it! (:

I would convert 130.4 J to L*atm then use w = -pdV as you've indicated. I think the answer is about 1300 mL or so.
