From the given statements, 2 moles of KO2 appears to react with 1 mole of CO2
We can determine the mass of KO2 using the mass of CO2 and their molar masses via stoichiometry
Potassium superoxide, KO2, is often used in oxygen masks (such as those used by firefighters) because KO2 reacts with CO2 to release molecular oxygen. Experiments indicate that 2 mol of KO2 (s) react with each mole of CO2(g).
What mass of KO2(s) is needed to consume 19.0 g CO2(g)?
