What is the chemical formula for normal AIR?

Question

Water is H2O
Carbon dioxide is Co2
Normal atmospheric air has oxogen, nitrogen, and carbon dioxide, plus some other stuff.
I know it is not just O2, which woiuld be pure oxogen.
I guess to make it easier I would request the answer be for sea level and about 29 degrees of atmospheric pressure.
This is my first question so be kind, no spam or BS.

Answer 1

Air is not a molecule or elemental compound. it is a mixture of many different things--similar to an emulsion--that do not react to one another, including, but not limited to: CO2, O2, N2, H2O VAPOR, AR...

Component Symbol Volume
Nitrogen N2 78.084%
Oxygen O2 20.947%
Argon Ar 0.934%
Carbon Dioxide CO2 0.033%

THE ABOVE 4 MAKE UP 99.998%

Neon Ne 18.2 parts per million
Helium He 5.2 parts per million
Krypton Kr 1.1 parts per million
Sulfur dioxide SO2 1.0 parts per million
Methane CH4 2.0 parts per million
Hydrogen H2 0.5 parts per million
Nitrous Oxide N2O 0.5 parts per million
Xenon Xe 0.09 parts per million
Ozone O3 0.07 parts per million
Nitrogen dioxide NO2 0.02 parts per million
Iodine I2 0.01 parts per million
Carbon monoxide CO trace
Ammonia NH3 trace

Answer 2

Contrary to your examples, air is not a chemical compound, but a mixture of gases.

The composition of air is typically (at sea level, RT, and 1 atm)

Nitrogen N2 78.084 %
Oxygen O2 20.9476 %
Argon Ar 0.934 %
Carbon Dioxide CO 20.0314 %
Neon Ne 0.001818 %
Methane CH 40.0002 %
Helium He 0.000524 %
Krypton Kr 0.000114 %
Hydrogen H2 0.00005 %
Xenon Xe 0.0000087 %

Answer 3

It's 78% N2, 21% O2, and 1% Ar for dry air.

Wet, humid air can have several % water vapor (H2O), it is always higher with warmer air.

Answer 4

There is no chemical formula because air is not a compound. It is comprised of many compounds, one of them being O2.
This table gives the composition of dry air by mole percentage:
