I am having trouble figuring this question out.

The decomposition of potassium chlorate, KCIO₃, is used as a source of oxygen in the laboratory. Potassium chloride is also produced. How many moles of potassium chlorate are needed to produce 15 mol of oxygen?

1.First develop the equation for this reaction. All compounds are given.
2.Then look the relationship of the moles between chlorat and oxygen
3.Convert this to the demanded value of 15 mol.
4.Post your work and result here
