Dry air contains roughly (by volume): All the above are relatively small, light, non-polar molecules, characteristics mimicking an ideal gas. At normal ambient conditions such as standard temperature and pressure, most real gases behave qualitatively like an ideal gas.
A small bubble of gas remained [mostly argon]. Cavendish wrote that this bubble âwas not more than one hundred and twentieth of the bulk of the phlostigated air [nitrogen].â (1) So, Cavendish is saying that air is at least 99.3 percent nitrogen/oxygen/carbon dioxide with a maximum 0.7 percent of something else.
