The atmosphere surrounding the Earth is a mixture of gases. In some places, human activities have added other gases to the atmosphere, which are called pollutants.

Unpolluted air

The Earth is surrounded by a mixture of gases called the atmosphere. The main gases in the atmosphere, and their approximate percentages in dry air, are shown below.

The composition of air

The atmosphere also contains a small but important amount of carbon dioxide, approximately 0.04 per cent, and tiny amounts of a few other gases.

In addition to these gases, the air also contains water vapour. The percentage of water vapour varies from one location to another, and according to weather conditions. This is why the percentages of the other gases are usually quoted for dry air.

Answer 2

Final answer: Most important and abundant compound in unpolluted air is water vapour having chemical formula $H_{2}O(g)$.    

Given that: We are given the term unpolluted air.

To find: We have to find the formula of a compound in unpolluted air.

Explanation:

• Unpolluted air is the clean air which not affected by pollution.
• Actually there is no particular chemical formula for air because clean air does not consists of the same components, is a mixture of many different type compounds.
• Like mixture, the components of air can be separated by using physical methods, such as fractional distillation.
• The components of air are water vapour, oxygen, nitrogen, argon carbon dioxide, methane, nitrogen oxides,..etc.
• Water vapour is the most important and abundant compound in unpolluted air and is present at levels which vary between 0.1% to 5% depending on temperature and humidity conditions.

• Most important and abundant compound in unpolluted air is water vapour having chemical formula $H_{2}O(g)$.

Hence, formula of a compound in unpolluted air is $H_{2}O(g)$.
