The reaction between potassium superoxide, KO2
, and
CO2
,

4
KO2
+2
CO2
→ 2
K2CO3
+3
O2

is used as a source of
O2
and absorber of
CO2
in 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?
