according to the balanced reaction equation:

2KClO3→ 2KCl + 3O2 

from this equation, we can see that the molar ratio between KCl & O2 is 2 : 3

so, 2 moles of KCl will need 3 moles of O2

∴  7.16 moles of KCl will need X moles of O2

∴number of moles of O produced = 7.16 * 3 / 2

                                                        = 10.74 moles
