Each 100 cm3 of air, constitutes 78cm3 nitrogen, 21cm3 oxygen and 1cm3 constitutes of other gases like Argon, ozone, carbon dioxide and water vapour in small amounts.
Dry air contains 78% nitrogen , 21% oxygen and 1%noble gases.
In 100 cm³ of air, there are approximately 78 cm³ of nitrogen, 21 cm³ of oxygen, and 1 cm³ of other gases. This composition is essential for life and remains fairly constant in the atmosphere. Understanding these proportions allows us to appreciate the balance essential for various biological and chemical processes.
