Explain the partial pressures of co2 and h2o in exhaled air

Reference no: EM13294550

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 27.0 torr at 30.6°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? (Note: 8 h has 1 significant figure, so round your answer to 1 sig. fig.)
