Chapter 5, Problem 36QAP

Potassium peroxide is used to absorb the CO₂ produced by the people in a space vehicle.

${\text{2K}}_{\text{2}}{\text{O}}_{\text{2}}\left(s\right)+{\text{2CO}}_{\text{2}}\left(g\right)\to {\text{2K}}_{\text{2}}{\text{CO}}_{\text{3}}\left(s\right)+{\text{O}}_{\text{2}}\left(g\right)$If a person at rest exhales 3.0 L of air per minute and CO₂ is 3.4% (by volume) of exhaled air, how many grams of K₂O₂ are needed per person for a five-day trip. Assume a temperature of 250 and 728 mm Hg pressure.
