Answer:

Per order of the gas amount present in the atmosphere and in accordance with what was reported by the NASA we can find expressed in proportion, the following gases:

Molecular Nitrogen--------0,7808

Molecular Oxygen---------0,2094

Argon---------------------0,00934  

Carbon Dioxide----------0,00035

Neon-----------------0.00001818

Helium--------------0.00000524

Methane--------0.00000170

Krypton---------0.00000114

Hydrogen-------0.00000055

Explanation:

The Earth’s atmosphere is composed of many gases. Nitrogen is the main constituent gas, which represents around of 78% or 0,78 in proportion. Per order of the gas amount present in the atmosphere and in accordance with what was reported by the NASA we can find expressed in proportion, The following gases:

Molecular Nitrogen--------0,7808

Molecular Oxygen---------0,2094

Argon---------------------0,00934  

Carbon Dioxide----------0,00035

Neon-----------------0.00001818

Helium--------------0.00000524

Methane--------0.00000170

Krypton---------0.00000114

Hydrogen-------0.00000055

In addition of these gases, small amounts of water vapor can be present to.
