An ideal gas at 26.3°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. Your response differs from the correct answer by more than 10%. Double check your calculations. mol (b) The gas pushes against a piston, expanding to twice its original volume, while the pressure falls to atmospheric pressure. Find the final temperature. K
