I'm having some trouble getting started on this one: 3.00×10^4 cm^3 of 300 degrees C steam at a pressure of 10.0 atm is cooled until it condenses. What is the volume of the liquid water? Give your answer in cm^3. I figure you use pV=nRT to solve. I've been trying to rearrange it, but am confused. Any help would be greatly appreciated. Thanks.
