The reaction between potassium superoxide, KO₂, and CO₂,

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 0.300 mol of KO₂ reacts in this fashion?

Explanation:

1. Balanced chemcical reaction (given):

2. Mole ratio

Use the coefficients from the balanced chemical equation to form the mole ratio of O₂ to KO₂:

3. How many moles of O₂ are produced when 0.300 mol of KO₂ reacts in this fashion?

Mutiply 0.300 mol of KO₂ by the mole ratio:

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .
