The space shuttle environmental control system handles excess CO2 (which the astronauts breathe out; it is 4.0% by mass of exhaled air) by reacting it with lithium hydroxide, LiOH, pellets to form lithium carbonate, Li2CO3 , and water. If there are four astronauts on board the shuttle, and each exhales 20. L of air per minute, how long could clean air be generated if there were 28,000 g of LiOH pellets available for each shuttle mission? Assume the density of air is 0.0010 g/mL.
