A person inhales air richer in O2 and exhales air richer in CO2 and water vapor. During each hour of sleep, a person exhales a total of 300. L of this CO2-enriched and H2O-enriched air.
(a) If the partial pressures of CO2 and H2O in exhaled air are each 29.5 torr at 35.6°C, calculate the masses of CO2 and of H2O exhaled in 1.00 hour of sleep.
CO2
H2O
(b) How many grams of body mass does the person lose in about 8 h sleep if all the CO2 and H2O exhaled come from the metabolism of glucose? C6H12O6(s) + 6 O2(g) 6 CO2(g) + 6 H2O(g)
