Air enters in the lungs in a tiny cavity called alveoli. Oxygen diffuses into our blood from alveoli. The average radius of alveoli is 0.005 cm and air inside it contains 21% `O_(2)` and 79% `N_(2)`. Assuming that the pressure in the aveoli is 1 atm at body temperature of `37^(@)C`.
Volume of single alveoli is :

Air entering the lungs ends up in tiny sacs called alveoli.From the alveoli, the oxygen diffuses into the blood. The average radius of the alveoli is 0.0050 cm and the air inside contains 14 per cent oxygen. Assuming that the pressure in the alveoli is 1.0 atm and the temperature is 37^(@)C , calculate the number of oxygen molecules in one of the alveoli.
