Question

Sodium peroxide is sometimes used in emergency breathing devices on submarines since that compound will react with carbon dioxide to produce oxygen and sodium carbonate. Answer the following questions if we assume that one person produces about 10.0 moles of carbon dioxide to produce oxygen and sodium carbonate. Answer the following questions if we assume that one person produces about 10.0 moles of carbon dioxide in a 24 hour period.
a) How many moles of oxygen are produced per day for one person who requires the emergency breathing device?
b) How many grams of sodium peroxide are required to remove 10.0 moles of carbon dioxide?

If you are going to answer the question actually give the right answer instead of a couple of words with dot dot dot just to get credit. Thank you!!

Answer 1

OK, so the reaction would be 2(Na2O2) + 2(CO2) --> 2(Na2CO3) + O2.

a) each mole of CO2 produces half a mole of O2, so each person would get 5 moles per day of oxygen.

b) You need a mole of Na2O2 for each mole of CO2, so ten moles total. The molar mass of Na2O2 is 2*22.990 + 2*15.999, or 77.978 g/mol. Therefore 10 moles of Na2O2 weighs 779.78 grams, which is how much you need.
