- In the lungs, a thin respiratory membrane separates tiny sacs of air from the blood in the capillaries at atmospheric pressure. These sacs are called alveoli (spherical shape), and it is from them that oxygen enters the blood. The diameter of the alveoli is 0.25 mm, and the air inside contains 14% oxygen. If the air behaves as an ideal gas at body temperature of 37 °C, find the number of oxygen molecules in one of the sacs?arrow_forwardTwo containers of equal volume each hold samples of the same ideal gas.
