Due to my calculations, it seems that there is a direct correlation between the ammount of molecules in a closed space and the pressure of the closed space, whether or not the species are light or heavy. The more molecules in the closed space, the higher the air pressure becomes. I also noticed that the more molecules that were in that closed space, the faster the molecules moved, thus increasing the temperature inside the closed space. Possible sources of error were not present because I did this experiment on  a computer.
