Nitrogen makes up about 78 of Earth's atmosphere because it is a stable and non-reactive gas that is not easily used up by living organisms or chemical processes.
Approximately 78% of the air is nitrogen, so if you have 2 liters of oxygen, it would suggest you have around 78% of nitrogen, which would be about 5.5 liters (calculated as 2 / 0.22 = 9.09 liters of air in total, 78% of that is nitrogen).
Nitrogen is four fifths of the air so their densities are very similar. Pure nitrogen is slightly less dense than air.
A common misconception is that air is mostly oxygen. 78% of air is nitrogen and only 20% is oxygen. Nitrogen is inert and flows in and out of our lungs untouched, but we require oxygen to live, so it gets absorbed.
Nitrogen can be extracted from air through a process called fractional distillation. This involves cooling the air to liquefy it, then gradually warming it up to separate the nitrogen from other gases like oxygen and argon.
One way to extract nitrogen from air at home is through a process called fractional distillation. This involves cooling the air to liquefy it, then gradually warming it up to separate the different components, including nitrogen. The nitrogen can then be collected as a gas.
There is about 78.09% of nitrogen in the air.
Approximately 78 of the air we breathe is nitrogen.

Air is 78% nitrogen, and most tyres are inflated with air, so mixing pure nitrogen with air would not be a problem.
The air we breathe is composed of approximately 78% nitrogen. This nitrogen is vital for many biological processes, but is generally inert and does not react with other components in the air.
Air is about 78% nitrogen pretty much everywhere on Earth.
Air contains about 78% nitrogen by volume.
The air is already 78% nitrogen, so nitrogen doesn't pollute air. That being said, the nitrogen in air reacts under high heat and/or pressure such as an engine or combustion process to make nitrogen oxides which are toxic or can combine with water to make acid rain, or combine with reactive hydrocarbons in the presence of ultraviolet light to make photochemical smog.
If that were so then fires would burn much more intensely.
Dry air is about 80% nitrogen. The remaining 20% consists mostly of things that are heavier than nitrogen, so dry air is very slightly heavier than nitrogen.
Nitrogen makes up about 78% of the Earth's atmosphere.
Nitrogen makes up about 78% of Earth's atmosphere, so when you breathe air, approximately 78% of it is nitrogen.
