Dear student
Air is not supposed to be considered as a pure substance. Because air is a mixture of different gases. - Air mostly contains nitrogen and oxygen in about 78% and 20% respectively. Note: Elements and compounds have a constant composition throughout and can thus be said as pure substances.
