A man jogging has a metabolic rate of 658 W.
(a)
Calculate his volume rate of oxygen consumption in L/s.
? L/s
(b)
Estimate his required respiratory rate in breaths/min if his lungs inhale 0.620 L of air in each breath and air is 20.9% oxygen.
?breaths/min
The partial pressure of oxygen in the lungs is about 150 mm of Hg. (The partial pressure is the pressure of the oxygen alone, if all other gases were removed.) This corresponds to a concentration of 5.3 × 1024 molecules per m3. In the oxygen-depleted blood entering the pulmonary capillaries, the concentration is 1.4 × 1024 molecules per m3. The blood is separated from air in the alveoli of the lungs by a 1-μm-thick membrane. What is the rate of transfer of oxygen to the blood through the 5 × 10-9 m2 surface area of one alveolus? Give your answer in both molecules/s and μmol/s. Assume The diffusion coefficient for oxygen in tissue is 2 × 10-11 m2/s. What is the same rate of transfer in μmol/s. Give your answer to 1 significant figure.
Calculate: (a) the number of moles in 1.00 m3 of gas at STP, and (b) the number of liters of gas per mole.
