We know, the ideal gas equation,
PV =nRT
Here,
n is the number of moles
V is the volume
T is the temperature.
P is the Pressure.
Now, Volume, temperature are given constant.
and the number of molecules is also the same for all flasks.
Thus, the pressure of the gas in all the flasks will be the same. Since the pressure depends on the number of moles( number of molecules related to moles by Avogadro's number) of the gases and not on the individual elements.
