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
Step-by-step 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.
