4 KO2(s) + 2 H2O(g) + 4 CO2(g) 4 KHCO3(s) + 3 O2(g)

Solid potassium superoxide, water vapor, and carbon dioxide gas react to form solid potassium bicarbonate and oxygen gas according to the reaction above. This reaction can be utilized in emergency oxygen masks. Exhaled water vapor and carbon dioxide react with potassium superoxide in the mask to produce oxygen. If someone using one of those masks exhales 0.716 g of CO2/min, how many grams of potassium superoxide would be consumed in 12.00 minutes?
