APOLLO 13 LUNAR MİSSION
There are three steps needed for these calculations:
1)
Convert grams – moles (using the molar mass of the known).
Convert moles of known (from step 1) –→ moles of unknown using the mole ratio
(from balanced chemical equation).
2)
3)
Convert moles of unknown (from step 2) → grams using molar mass of the
unknown).

You are a NASA engineer. You are the chief engineer for the Apollo 13 mission to the
moon. The astronauts are running out of oxygen and need to get rid of the excess
carbon dioxide. You know that sodium hydroxide has been suggested as a means
of removing carbon dioxide from the spacecraft cabin. The filter which they had
been using is fully saturated and no longer works. You remember that the astronauts
have a 3.000 g container of sodium hydroxide (NAOH) on the ship. You also know
that sodium hydroxide can be used to remove carbon dioxide
according to the following reaction:
NaOH + Cо, Na,co, + H,0
-How many grams CO, can be removed from the ship
with the 3,000 g of NaOH?
- The astronauts have 2 days left before they land on
earth. You know that the astronauts will emit
roughly 1,000 grams of CO, each day. Is there enough
sodium hydroxide in the cabin to cleanse the cabin air
of the carbon dioxide, or are the astronauts doomed?
Again be sure to show all your work.
