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) ?
