Nearly all of the Earth's atmosphere is made up of only five gases: nitrogen, oxygen, water vapor, argon, and carbon dioxide.Several other compounds are also present. Although this CRC table does not list water vapor, air can contain as much as 5% water vapor, more commonly ranging from 1-3%.The 1-5% range places water vapor as the third most common gas (which alters the other percentages ...
