An idiot called "ALP" has come up with his own theory of "weight" in
order to justify his claim that CO2 is weightless......
The pressure exerted by a volume of an ideal gas at a given temperature is a constant. It depends *not* on the weight of the
molecules but on the *number* of molecules and their energy(T).
Since all of the components of a volume of air will be at the same temperature, they will exert the same pressure. In other words,
irrespective of the weight of the *molecules*, the weight of the gas will be the *same* since it is purely based on the pressure.
Moreover, the molecules will exert the same pressure at the top of a container of air that they do at the bottom, so any scale
will show zero.
This is not my 'position'. It is a simple description of the model which applies at standard temperature and pressure in the
atmosphere.
ALP thinks the ideal gas law means gases are weightless!!!!
Note the bit "In other words, irrespective of the weight of the *molecules*, the weight of the gas
will be the *same* since it is purely based on the pressure."

Also, ALP thinks a container of air is weightless because there is no pressure
difference between the top and the bottom!!!!!

A novel theory indeed..............

But the number of molecules varies with the density of the gas.

<<"Moreover, the molecules will exert the same pressure at the top of a container of air that they do at the bottom, so any scale

Umm no, because of gravity there are more gas molecules on the bottom of the container than the top.
What you are referring to is the "perfect gas model" used to calculate hydraulic pressure and the like.
