Best Answer: A real gas molecule has a shape and a finite size. An ideal gas molecule (imaginary) is a point with no shape and it occupies no space. A real gas molecule interacts with others.
One mole of an ideal gas has a volume of 22.7 L at STP as defined by IUPAC. At normal conditions such as standard temperature and pressure, most real gases behave qualitatively like an ideal gas. Many gases such as nitrogen, oxygen, hydrogen, noble gases, and some heavier gases like carbon dioxide can be treated like ideal gases within reasonable tolerances.
