A self-contained breathing apparatus uses potassium superoxide, KO2, to convert the carbon dioxide and water in exhaled air into oxygen, as shown by this equation.
4 KO2 (s) + 4 CO2 (g) + 2 H2O (g) → 4 KHCO3 (s) + 3 O2 (g)
How many molecules of oxygen gas will be produced from the 0.0468 g of carbon dioxide that is exhaled in a typical breath?
a) 4.8 x 1020
b) 6.4 x 1020
c) 8.5 x 1020
d) 1.9 x 1021
