Help with gas problem
« on: March 18, 2008, 09:30:21 PM »
7.25 x 10^22 molecules of methane are in a rigid walled container at 145 degrees C. How many moles are present if the pressure drops to 1/5 the original pressure and the temperature drops to
-115 degrees C? Did gas leak out or was gas added?

Thanks in advance!
