A cylinder with a moveable piston holds 2.40 mol of argon at a constant temperature of 295 K. As the gas is compressed isothermally, its pressure increases from 101 kPa to 141 kPa. What is the final volume of the gas? I don't know where to begin. I tried using Pv=nRT: [(2.4)(8.31)(295)]/ 40 = 147.087. This is wrong. I wasn't sure if I use the difference in pressure and if I have to convert from kPa to Pa. Can anyone help?

You have to work this in Pascals, Volume will be in m3
