No, air now (2013) contains 400 ppm (parts per million) or 0.04%. This has risen since the Industrial Revolution, 200 years ago, from 280 ppm (parts per million) or 0.028% where it had been steadily for thousands of years.
if this is math and your asking what gas has a percent by volume 78.09 it is nitrogen
Oxygen is the second most common/abundant gas in the air that we breathe. Nitrogen is the most abundant gas in the air we breathe. The composition of air is often treated as 79 mole or volume percent N2 and 21 mole or volume percent O2.
Argon is the unreactive gas that makes up 1 percent of the Earth's atmosphere. It is a noble gas and is commonly used in applications where an inert atmosphere is required, such as in light bulbs and welding.
All plants that live above water do this.
A fuel gas containing about 5o percent carbon monoxide 40 percent hydrogen and small amount of methane, carbon dioxide and nitrogen made by passing stem and air over heated coke and coal.
If by 'our gas' you mean air, then roughly 78% of air is Nitrogen.

Dry air is just over 78% nitrogen gas.
The element that makes up approximately 0.9 percent of the air is argon. Argon is a noble gas and is the third most abundant gas in the Earth's atmosphere, following nitrogen and oxygen. It plays a minimal role in chemical reactions due to its inert nature.
Nitrogen. To be specific it takes up 78% of air whilst Oxygen takes up 21%. The remaining percentage consists of various gases including carbon dioxide.
Oxygen gas is the gas present in air that takes part in a combustion reaction. It acts as the oxidizing agent in the reaction.
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.
0.039 is carbon dioxide
