## Homework Statement

Calculate Work(w) when 6.5L of an ideal gas at an initial pressure of 34.3atm is expanded or compressed isothermally to a final volume of 34.3L reversibly. Answer in J

## Homework Equations

PV=nRT

P1V1=P2V2

w=-nRT In(V2/V1)

## The Attempt at a Solution

Using w=-nRT In(V2/V1)

I'm not given mols or T, I know T=constant, since it's isothermal

Can I use PV=nRT and substitute (PV) in for (nRT) in the equation: w=-nRT In(V2/V1) ?

If so, what should I use for values of P and V? Final/Initial/delta?

PS: This may be in the wrong place, the boundary seems unclear in Chem/Phys or Phys/Chem studies.
