Air entering the lungs ends up in tiny sacs called alveoli. It is from the alveoli that oxygen diffuses into the blood. The average radius of the alveoli is 0.0041 cm, and the air inside contains 14 percent 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 alveolus. For calculation purposes, assume that the average alveolus is a perfect sphere. Be sure your answer has the correct number of significant digits. Note: Reference the Fundamental Constants table for additional information. 8.486 x 10 10° | molecules x10
