Potassium superoxide ,`KO_(2)`, is utilised in closed system breathing apparatus. Exhaled air contains `CO_(2)` and `H_(2)O` ,both of which are removed and the removal of water generates oxygen for breathing by the reaction
`4KO_(2)`(s) + `2H_(2)O(l) to 3O_(2)(g) + 4KOH(s)`
The potassium hydroxide removes `CO_(2)` from the apparatus by the reaction :
`KOH(s) + CO_(2)(g) to KHCO_(3)`(s)
(a) What mass of `KO_(2)` generates 24 gm of oxygen ?
(b) What mass of `CO_(2)` can be removed from from the apparatus by 100 gm of `KO_(2)` ?

Answer

(a) 71 gm (b) `61.97` gm
