If a gas "behaves" ideally, does that mean it is an ideal gas with no molecule volume or mass?

Question was, two containers. One has N2 and other has O2. If they behave as ideal gases, then their densities are NOT the same.

so a bit confusing because of terminology.

Ideal gasses do have mass. The particles/molecules have 0 volume but they do maintain their mass. Which would be one hint why such a situation is only ideal and not realistic.

oh i didn't know that! thanks.

Massless molecules -> zero kinetic energy -> no pressure, no temperature. That would be too ideal. 😉
