Question

Be sure to answer all parts.
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 about 300. L of this CO₂−enriched and H₂O-enriched air.
(a) If the partial pressures of CO₂ and H₂O in exhaled air are each 29.1 torr at 37.0°C, calculate the masses of CO₂ and of H₂O exhaled in 1 h of sleep.

_____g CO₂ _____ g H₂O

(b) How many grams of body mass does the person lose in 8 h sleep if all the CO₂ and H₂O exhaled come from the metabolism of glucose? Assume that the mass lost is equal to the mass of glucose that is converted to CO₂ and H₂O.

C₆H₁₂O₆(s) + 6 O₂(g) → 6 CO₂(g) + 6 H₂O(g)
