A self-contained breathing apparatus uses potassium superoxide, `KO_(2)`, to convert the carbon dioxide and water in exhaled air into oxygen, as shown by the equation: `4KO_(2)(s)+2H_(2)O(g)+4CO_(2)(g)to4HCO_(3)(g)+3O_(2)(g)`
How many molecules of oxygen gas will be produced from 0.0468 g of carbon dioxide that is exhaled in a typical breath?
