Step-by-step explanation:
To solve this question, we need to use the equation ratio between O2 and KClO3:
2KClO3 → 2KCl + 3O2
2 moles of KClO3 produces 3 moles of O2
So:
2 moles of KClO3 --- 3 moles of O2
7.46 moles of KClO3 --- x moles of O2
2*x = 3*7.46
x = 22.38/2
x = 11.19 moles
Answer: It will be formed 11.19 moles of O2.
