Which of the three single flasks do the molecules have the greatest mass?

Gases in chemistry are one of the three states of matter that have no defined volume or shape. Each gas has a standout behavioral pattern. This behavior can depend on many variables including temperature, size, and pressure. Though their actions are different, all gases act the same.

Particles are what makeup gas. These particles can be various things including molecules and atoms. There are multiple types of gases, including elemental gases, which are elements that become gases at standard pressure and temperature. Examples of elemental glasses include hydrogen, xenon, and krypton.
