Chemistry question? Someone explain..?

A self-contained breathing apparatus uses potassium superoxide, KO2, to convert the carbon dioxide and water in exhaled air into oxygen, as shown by the equation.
4 KO2(s) + 2 H2O(g) + 4 CO2(s) ---> 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?
