Question #97757

If you have two gases in two cambers that are separated by a narrow tube with a stopper in the tube that divides them, preventing the gases from mixing. One gas(xenon) has a pressure of 45.5 Kpa in the chamber with a volume of 2.00 L. The other gas ( argon) has a pressure of 55.5 kpa in the chamber with a volume of 4.00 L. If you pull the stopper out and allow the gases to mix:
A. What will be the new partial pressure of each gas?
B. What will be the total pressure of the new gaseous mixture?

Expert's answer

a) The partial pressure of xenon is 15.2 kPa, the partial pressure of argon is 37 kPa

b) The total pressure is 52.2 kPa
