The reaction between potassium superoxide (KO2, 71.1 g/mol) and CO2 is used as a source of oxygen in self-contained breathing equipment used by rescue workers: 4 KO2 (s) + 2 CO2 (g) -> 2 K2 CO3 (s) + 3 O2 (g) If the consumption of 7.50 g of KO2 in the presence of excess CO 2 results in the production of 0.065 moles of oxygen gas, what is the percent yield of this reaction?

Question
The reaction between potassium superoxide (KO2, 71.1 g/mol) and CO2 is used
as a source of oxygen in self- contained breathing equipment used by rescue
workers: 4 KO2 (s) + 2 CO2 (g) -> 2 K2 CO3 (s) + 3 02 (g) If the
consumption of 7.50 g of KO2 in the presence of excess CO 2 results in the
production of 0.065 moles of oxygen gas, what is the percent yield of this
reaction?
