Use the worked example above to help you solve this problem. An ideal gas at 23.6°C and a pressure 1.80 105 Pa is in a container having a volume of 1.00 L.
(a) Determine the number of moles of gas in the container
(b)The gas pushes against a piston, expanding to twice its original volume, while the pressure falls to atmospheric pressure. Find the final temperature. Not sure of which vaule of R to use. 8.31 J/mol * K or .0821 L *atm / mol * K
