According to the Avogadro’s law, equal number of moles of gases occupies the same volume at identical
condition of temperature and pressure. Even if we have a mixture of non-reacting gases then Avogadro’s
law is still obeyed by assuming mixture as a new gas.
Now let us assume air to consist of 80% by volume of Nitrogen (N2) and 20% by volume of oxygen (O2).
If air is taken at STP then its 1 mole would occupy 22.4 L. 1 mole of air would contain 0.8 mole of N 2 and
