When potassium bromate (kbro3 ) is heated, it decomposes into potassium bromide and a gas that supports the combustion of a glowing splint?

We know that the oxygen (O2) causes a glowing splint to reignite, however, let us check what is missing on the products side of the chemical equation: 
KBrO3 → KBr + ? 
As we see, oxygen (O2) is the element missing from the other side. Therefore the balanced chemical equation for this decomposition is as follows: 
2KBrO3 → 2KBr + 3O2 

58750.08068 is the answer i think

i think its 100.

hope this !
