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 also are 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%.
Is nitrogen heavier than air? A: Nitrogen is the major constituent of Earth's atmosphere, so it is, in a way, exactly as heavy as air. Though nitrogen makes up the bulk of the atmosphere by volume, almost 21 percent of the air is composed of molecular oxygen. To determine nitrogen's weight relative to air, it is important to determine whether the nitrogen in the atmosphere is lighter or heavier than the oxygen.
