3. The chemical equation for the decomposition of potassium chlorate is 2 KClO3(s) → 2 KCI(s) + 302(g) The molar masses of the elements in this equation are: K 39.1 g/mol, CI 35.4 g/mol, O 16.0 g/mol B. Using the Law of Conservation of Mass, how many grams of oxygen formed when 30.6g potassium chlorate decomposed?
