Chemistry Gas Laws Question?

Because a the molecular m of Diatomic Nitrogen (the form Nitrogen is always in) is lower than the m of Argon, there will be more molecules of nitrogen than there are atoms of argon. This translates to there being more moles of Nitrogen than Argon, and by PV=nRT, you can determine that the pressure in the Nitrogen flask will be greater than that in the Argon flask. Because the Nitrogen molecules are under greater pressure than the Argon molecules, they will be moving faster than the argon atoms. Because the Nitrogen molecules are moving faster than the argon molecules, it follows that they will also collide more frequently with the walls of the flask than the argon atoms will.
