Problem 3. An adult takes about 12 breaths per minute, inhaling roughly 500 mL of air with each breath. The molar compositions of the inspired and expired gases are as follows Species Inspired Gas (%) Expired Gas () О2 15.1 20.6 3.7 0.0 CO2 N2 77.4 75.0 Н-О 2.0 6.2 The inspired gas is at 24°C and 1 atm, and the expired gas is at body temperature and pressure of 37°C and 1 atm. Nitrogen is not transported into or out of the blood in the lungs, so that n(N2)in = n(N2]out a) Calculate the masses of O2, CO2, and H2O transferred from the pulmonary gases to or from the blood (specify which) per minute. b) Calculate the volume of air exhaled per milliliter inhaled. At what rate (g/min) is this individual losing weight by merely breathing? c)
