Some older emergency oxygen masks contains potassium superoxide `KO_2` which reacts with `CO_2` and water present in exhaled air to produce oxygen according to the given equation. If a person exhales `0.667 g` of `CO_2` per minute, how many gram of `KO_2` are consumed in `5.0` minutes ? `4KO_2 + 2H_2O + 4CO_2rarr4KHCO_3 + 3O_2`
