The reaction between potassium superoxide,
KO2, and CO2, 4 KO2+2 CO2 → 2 K2CO3+3 O2 is used as a source of and absorber of CO2in self- contained breathing equipment used by rescue workers.
How many moles of O2 are produced when 451 mL in a .518 M solution of KO2 reacts in this fashion?
How many grams of KO2 are needed to form 44 g of O2?
What volume of a 0.424 M CO2 solution are needed to produce 63.58 mL of 0.731 M solution of K2CO3?
