Some older emergency oxygen masks containing potassium superoxide (KO2)) react with CO2 and water in exhaled air to produce oxygen according to the given equation.
If a person exhales 0.667 g of CO2 per minute, how many grams of KO2 are consumed in 5.0 minutes?
The correct option is D 5.38
The number of moles of CO2 exhaled in 5 minutes.
. .. 4 mole of KO2 consumed by 4 mole CO2
mass of KO2=5×0.66744×71=5.38g
