hi i am aarya your answer is here
Inhaled air contains approx 21% oxygen, 0.04% carbon dioxide and 79% nitrogen while exhaled air contains approx 16% oxygen, 4% carbon dioxide and also 79% nitrogen. The only difference between them is the varying levels of oxygen and carbon dioxide. The inhaled air is actually a air.

Exhaled air contains less oxygen and more carbon dioxide, it is also saturated with water vapour. Exhaled air contains: 78% nitrogen. 16% oxygen.we can prove it through a activity.
Limewater Test - To check for carbon dioxide in your breath
1. Add 50 ml of lime water to two 100 ml beakers.
2. Bubble room air through one beaker for one minute using a pipe and pipe pump. Observe and record the results.
3. With the other beaker, bubble exhaled air through the solution for 1 minute. Try to bubble the air through the same rate that you did with the first beaker. After 1 minute record your results.
after this activity u will see that exhaled air contains more carbondioxide
