Alveolar gas is considered an ideal gas that it is located inside the alveolus and is composed mainly of β, β, HβO and β at 37Β°C and 760 mmHg. The total flow of β into the lung is 250.3 ml/min having an effective perpendicular area total of 36 mΒ² and a respiratory quotient (κββ/ββ) of -0.8. The partial pressure inside the alveolus of β and β are Pκββ = 40 mmHg and Pββ = 100 mmHg. Calculate the molar flow of β relative to the average molar velocity. Consider that 1 mol occupies 22.4 L at 37Β°C and at 760 mmHg and the vapor velocities of HβO and β are negligible in the alveolus. R = 8. 205 x 10β»β΅ mΒ³ atm/mol/K.
