A common laboratory preparation of oxygen (O) gas is the thermal decomposition of potassium chlorate (KClO3). Assuming complete decomposition, calculate the number of grams of O gas that can be obtained from 31.07 g KClO3. (The products are KCI and O). Be sure your answer has the correct number of significant digits.
