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 26.0 torr at 31.3°C, calculate the masses of CO2 and of H2O exhaled in 1.00 hour of sleep. CO2 .........g H2O .........g (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? (Note: 8 h has 1 significant figure, so round your answer to 1 sig. fig.) ........g C6H12O6(s) + 6 O2(g) 6 CO2(g) + 6 H2O(g)
