Problem: 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)?

FREE Expert Solution
  • 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
