Stoichiometry Help?

From the first equation you see that 4 moles of KO2 makes 4 moles of KOH. From the second, each mole of KOH removes one mole of CO2. Therefore, 4 moles of KO2 removes 4 moles of CO2. You know the KO2 m, so calculate the number of moles of KO2, which is the same number of moles of CO2 removed - so just calculate what m of CO2 that is!
