Dimensional Analysis Question
The Space Shuttle environmental control system handles excess CO2 (which the astronauts breathe out - it is 4.00% by mass of exhaled air) by reacting it with lithium hydroxide, LiOH, pellets to form lithium caronate, Li2CO3 and water. If there are 7 astronauts on board the shuttle, each exhales 20.0 liters of air per minute, how long could clean air be generate if there were 2.50E4 g of of LiOH pellets available for each shuttle mission? Assume the density of air is 0.00100 g/ml.
