Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly 78% nitrogen, (normally inert except upon electrolysis by lightning[1] and in certain biochemical processes of nitrogen fixation), 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and trace amounts of other gases, in addition about 1% water vapor. This mixture of gases is commonly known as air.
According to the National Center for Atmospheric Research, "The total mean mass of the atmosphere is 5.1480×1018 kg with an annual range due to water vapor of 1.2 or 1.5×1015 kg depending on whether surface pressure or water vapor data are used.

A very large no is tied up with the CO2 molecule. There is another part u are not counting. The gas Nitrogen when bombarded with alpha radiation will trans mutate to oxygen . That was one of our first real atomic experiments.

bilions and bilions and bilions. They're a lot. Imagine that 1 mole contains 6.022*10^23 molecules...and a mole correspond to 16 g...then think how much they can be ;)
