The percent of oxygen in dry air is approximately 21%.
Over 99 percent of the atmosphere in pure dry air is composed of nitrogen and oxygen, with nitrogen making up about 78 percent and oxygen around 21 percent. The remaining 1 percent is made up of trace gases such as argon, carbon dioxide, and neon.
It is. Dry air lacks water vapor, not oxygen.
Oxygen makes up 21 percent of the air by volume.
Air typically contains about 21% oxygen by volume.

Yes, there is less oxygen in humid air compared to dry air.
No, humid air does not have less oxygen compared to dry air. The amount of oxygen in the air remains the same regardless of humidity levels.
It is. Dry air lacks water vapor, not oxygen.
Dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases.
The composition of air is usually sated as a dry composition (without water vapour). About 21% is oxygen. The rest is mostly Nitrogen (78%) and Argon (1%). Carbon Dioxide at 300ppm is the next largest with other gases at trace amounts
Oxygen makes up 21 percent of the air by volume.
