Solution: Potassium chlorate (KClO3 molar mass 122.5 g/mol) decomposes into oxygen gas and potassium chloride. When 3.25 grams of potassium chlorate decomposes at 610 torr and 34oC, what is the volume of oxygen gas produced? Remember to convert torr to atm and Celsius to Kelvin.2KClO3 (s) → 3O2(g) + 2KCl (s).
