Oxygen masks for producing O2 in emergency situations contain potassium superoxide, KO2. It reacts with carbon dioxide and water in exhaled air to produce oxygen:
4 KO2(s) + 2 H2O (g) + 4 CO2(g) → 4 KHCO3(s) + 3 O2(↑)
If a person wearing such a mask exhales 0.702 g CO2/min, how many grams of KO2 is consumed in 10.0 minutes? Please show all the work step by step and give the explanation.
