78 percent
Air is mostly gas
The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.
The maximum percentage of nitrogen by mass is about 78.08%, which is the composition of nitrogen gas (N2) in the atmosphere.
About 78% of air is Nitrogen.
The percentage of nitrogen in pure, dry ,standard air is 78,084 % (by volume).
78% of air breathed is nitrogen
Dinitrogen Pentoxide is made up of nitrogen and oxygen. The percentage of composition of each of these elements is: 25.936% nitrogen and 74.064% oxygen.
Nitrogen (symbol N2) makes up 78% of the composition of air.
Ammonia (NH3) has a percentage composition of 82.35% nitrogen and 17.65% hydrogen.
nitrogen-65% and oxygen-30 to 34%
gas composition in air is the sum of the gas individual element and that of the air i.e oxygen and nitrogen
The composition of liquid air is: 80 % nitrogen, 19 % oxygen 0,9 % argon, 0,1 % minor gases.
Nitrogen makes up about 78% of Earth's atmosphere.
This is the composition of the air.
