A rigid container whose volume can be varied with the use of apiston contains 2.53 mol H₂ gas at STP.
(a) What is the volume of the gas?
___L

(b) The container is cooled to 209 K. The piston is held fixed sothe volume does not change. What is the new pressure inside thecontainer?
atm

(c) The temperature of the container is held at 209 K and 1.55 molHe gas is added to the container. The pressure inside the containeris held constant, but the piston is released so the volume of thecontainer can vary. What is the final volume of thecontainer?
_ L

(d) What are the partial pressures of H₂ and He in thecontainer in part (c)?
H₂:
He:

(e) The piston on the container in part (c) is set to maintain aconstant pressure of 1 atm. The container is then heated from 209 Kto 380 K.What is the minimum amount of heat that must be added tothe container for it to reach 380 K?
____ J
