Hey mate

It greatly depends on the person, but on average it’s composed of 79% Nitrogen, 21% Oxygen and about 0.03% Carbon Dioxide[1], plus 1% of other compounds.

The air we breathe in is about 79% Nitrogen, 21% Oxygen and only 0.04% Carbon Dioxide, so exhaled air is quite concentrated in Carbon Dioxide.
It will help u

Thanku..

umm... we exhale all the gases in the air as air is a mixture of gases.... but there is a lot of oxygen present so, the gases which we don't need are exhaled out
