Help ; You are the chief NASA engineer for the Apollo 13 mission to the moon. The astronauts have oxygen available on board but need to get rid of the expelled carbon dioxide, otherwise they will eventually suffocate. There is a lithium hydroxide (LiOH) filter that has been added to the spacecraft as a means of removing carbon dioxide (CO2) from the cabin. __2__ LiOH(s) + __1__ CO2 (g)→ _1___Li2CO3 (s) + __1_ H2O (l)

1.The filter aboard the spaceship contains 265 moles of lithium hydroxide. How many moles of carbon dioxide will this amount remove from the spaceship’s cabin?

2.The astronauts have two (2) days left before they land on Earth. There are three (3) astronauts, and each astronaut emits approximately 15 moles of carbon dioxide each day. How much carbon dioxide will they expel during the two (2) day flight back to Earth?

3.Is there enough lithium hydroxide in the filter to cleanse the cabin air of the carbon dioxide, or are the astronauts doomed? Support your answer with your calculations and answers from above.

4.If the astronauts survive, they are not out of the woods yet! The spacecraft is sensitive to imbalances in weight when it re-enters the Earth’s atmosphere, therefore they need to be aware of the waste produced when they use the lithium hydroxide filter. The water from this reaction can be released prior to entry, however the solid lithium carbonate will need to be stored. The spacecraft can only account for an additional 7.5 kg before the balance will be altered causing landing problems. Can the astronauts re-enter the Earth’s atmosphere safely or is too much solid waste produced when using the lithium hydroxide filter?
[ 1 mole of Li2CO3 = 75 grams Li2CO3 ]
