Potassium chloride contains the elements potassium and chlorine. WHERE is the oxygen ?!?

You don't mean chloride.

Write a balanced equation.

See how many moles you have of starting material, and how many moles oxygen that will give you.

To go frm g to moles, divide by formula mass.

None because there is no oxygen in KCl.
