The interaction of O3 with KOH gives ozandies according to the following equation.
3KOH(s) + 2O3(g) =2KO3(s) + KOH . H2O (s) + 1/2 O2 (g)
The ozonide KO3 slowly decomposes to the products shown in the reaction below.
2KO3(s) = 2KO2 (s) +O2 (g)
What mass of KO2 will be produced by the reaction of 75.0 g of KOH?
