A cylinder with a moving piston expands from an initial volume of 0.350L against an external pressure of 2.70atm . The expansion does 251J of work on the surroundings. What is the final volume of the cylinder?

Answer 1

251J x (1 L*atm/101.325 J) = 2.48 L*atm
work = -p(V2-V1)
-(-2.48) = 2.7(V2-0.35)
Solv for V2 in L.
