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.
(b) How many grams of body mass does the person lose in 8 h of sleep if all the CO₂ and H₂O exhaled come from the metabolism of glucose? C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(g)
