The percentage of nitogen in outdoor air is 78%. 21% is oxygen, and 1% is water vapor, argon, carbon dioxide, and other gases.
Our air is about 79% Nitrogen.
87% of nitrogen is in the air
Air is 78% nitrogen
21 percent
78%
If by 'our gas' you mean air, then roughly 78% of air is Nitrogen.
21%
78%
The answer is.................AIR
78% in air.
Because air is composed of nitrogen (not 100% mind you) and when you exhale air, you also exhale nitrogen.
78 percent Air is mostly gas The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.
