Assuming a decomposition reaction with this equation: 2KClO3(s) --> 2KCl(s) + 3O2(g), the ratio is 2:3, and if you produce 15mol O2, then 10mol potassium chlorate are needed.
2 K + Cl2 = 2 KClOxygen is not needed.
This may be a trick question, electrolyis of a sodium chloride solution produces chlorine at the anode but does not produce sodium at the cathode. Electrolysis of molten sodium chloride does however produce sodium and chlorine.
Since molecules of potassium contain only single potassium atoms, molecules of iodine contain two atoms, and moles of potassium iodide contain one atom of each element, 2.5 moles of iodine are needed to react completely with 5 moles of potassium.
Water is not "softened" by potassium chloride, whether this salt is already present in the water or is added to it. The cause of water hardness is the presence in the water of divalent cations, primarily magnesium and calcium, which form almost totally water insoluble salts with the fatty acid anions of soaps. The fatty salts of these monovalent cations such as potassium are much more soluble in water. Therefore, water is softened by replacingdivalent cations in the water by monovalent cations. Such replacement can be accomplished by contacting the hard water with a cation-exchange resin preloaded with potassium chloride, or any other water soluble sodium or potassium salt. Whether such water is "better for your hair" is a subjective judgment, but such replacement does allow thoroughly cleaning the hair with a smaller amount of soap than would otherwise be needed.

A table salt substitute such as potassium chloride may be effective.
All salts soluble in water can exist also in organisms.
2 K + Cl2 = 2 KClOxygen is not needed.
Four moles of potassium chlorate are needed.
One of each K+ + I- -----> KI.
530,3 g potassium iodide are needed.

More than 45,5 g KNO3.
These reagents doesn't react.
Sodium chloride is not needed in phosynthesis.
