When you inhale air the concentration is abut 21% of oxygen but in your lungs some of it gets consumed and replaced by carbon dioxide the concentration of exhaled oxygen depends on your metabolism and oxygen consumption.
The oxygen you exhaled is about 16-17% of the air exhaled, and the carbon dioxide is about 4%.
When you inhaled, the oxygen was about 20-21% of the air, and the carbon dioxide is negligible.
Most of the rest of the air is nitrogen.
Air contains roughly 78% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, trace amounts of other gases, and a variable amount (average around 1%) of water vapor.
the amount of oxygen exhaled is 16.4% though carbon dioxide only 4.4%
The average percentage of CO2 in exhaled air was found to be 5%.

The diagram shows four gas-jars. Each contains a different gas. Burning magnesium is put into each jar. air,exhailed air, nitrogen, oxagen
A gas.
21% of the air is oxygen
80%
Ammonia is collected in inverted gas jar because it is lighter than air.

Air contains approximately 78% nitrogen gas.
78.09% Nitrogen by Volume (approx)
About 79% of earth's atmosphere is Nitrogen.
Nitrogen, close to 80 %.

Yes. A high amount of methane (fart) can pollute the air as it is still gaseous. An example of this is that cows alone produce a percentage of methane as they "fart" many times each day as they usually let out a lot of gas.
