A sample of KCIO3 weighing 4.55g is strongly heated. All of the oxygen gas given off is collected over water in a flask. The atmospheric pressure is 29.06inches of mercury. The temperature is 23 degrees C. The gas constant is 0.0821 (L)(atm)(K)(mol). What is the volume of water that is expected to be displaced by the oxygen gas (in Liters)? The equation for the reaction is2KClO3->2KCl+3O2
