Answer and Explanation:
How to Calculate the Percent Abundance of an Isotope
Step 1: Find the Average Atomic Mass. Identify the atomic mass of the element from your isotopic abundance problem on the periodic table. ...
Step 2: Set Up the Relative Abundance Problem. ...
Step 3: Solve for x to Get the Relative Abundance of the Unknown Isotope. ...
Step 4: Find percent abundance.
Keep in mind that when two moles of potassium chlorate are decomposed, 3 moles of oxygen are produced.Think of the coefficients: since the mole ratio is 2 to 3, it means that<span> 2 mol KClO3 will turn into 3 mol O2.

2kclO3->2kcl+3O2
