The solution to your problem is as follows:
<span>2 KClO3 → 2 KCl + 3 O2
</span><span>MW of KCL = 39.1 + 35.35 = 74.6 g/mole
62.6/74.6 = 0.839 moles KCl produced
0.839 moles KCl x 3O2/2KCl x 32g/mole O2 = 40.27g of O2 was produced
</span>
Therefore, there are <span>40.27g of O2 produced during the reaction.
</span>

We produce formaldehyde for medicinal purposes and synthesizing polyester.
Formaldehyde is a compound that is required in about 1.5 ounces in quantity as a normal part of our metabolism.
Also formaldehyde is used as a catalyst in the formation for the synthesis of many polyesters.
Formaldehyde also has many uses such as fungicide, germicide, disinfectant and as a preservative in mortuaries as well as important chemical in medical Laboratories.
In everyday items press fabric paints coating and paper base products also includes formaldehyde.
