Question

The air entering the lungs passes through tiny sacs called alveoli, from which oxygen diffuses into the blood. The average radius of the alveoli is 0.0050 cm, and the air inside contains 14 mole percent oxygen. Assuming that the pressure in the alveoli is 1.0 atm and the temperature is 37oc37oc; calculate the number of oxygen molecules in one of the alveoli.
