First calculate the molar mass of the potassium chlorate
KClO3 K is 39.1, Cl is 35.45 and O is 16 x 3 =48
The molar mass for one mol is 122.55g/mol
The percent composition is the part the oxygen contributed divided by the total molar mass times 100(to convert a decimal to a percent)
48/122.55 x 100 is 39.167%
Potassium Chlorate is 39.167 percent oxygen

How do you calculate the theoretical mass percentage of oxygen in potassium chlorate?
I believe it is: %O=mass of 3 mol of O / mass of 1 mol of potassium chlorate *100% If you measured it: %O=mass of oxygen lost / mass of potassium chlorate *100%
How oxygen is prepared in lab using potassium chlorate?
Potassium Chlorate, when heated gives Potassium Chloride and Oxygen. You can use Manganese Dioxide as a catalyst to speed up the reaction.
Decomposition of potassium chlorate to potassium chloride?
Potassium chlorate contains potassium, chlorine, and oxygen. It is used in safety matches, explosives, as an oxidizing agent, to prepare oxygen, and as a disinfectant.
What is the name or formula the gas evolved in heating of potassium chlorate?
Oxygen
What elements does potassium chlorate contain?

Decomposition of potassium chlorate to potassium chloride?
Potassium chlorate contains potassium, chlorine, and oxygen. It is used in safety matches, explosives, as an oxidizing agent, to prepare oxygen, and as a disinfectant.
How many grams of potassium chlorate would be produced by reacting 500 grams of potassium chlorate with oxygen gas?
Nothing is produced, 500g potassium chlorate will be the same 500 g potassium chlorate after reaction. Actually there is no reaction at all.
What is potassium chlorate used for?
it is used to prepare oxygen
How much oxygen gas in grams can be prepared from 86.8 g of potassium chlorate?
Pure oxygen gas can be prepared in the laboratory by the decomposition of solid potassium chlorate to form solid potassium chloride and oxygen gas. 34.0 g
How many moles of potassium chlorate must be used to produce 6 moles if oxygen gas?
Four moles of potassium chlorate are needed.
