Liquid oxygen was first prepared by heating potassium chlorate, KClO 3, in a closed vessel to obtain oxygen at high pressure. The oxygen was cooled until it liquefied. 2 KClO 3 ( s ) → 2 KCl ( s ) + 3 O 2 ( g ) If 171 g of potassium chlorate reacts in a 2.70-L vessel, which was initially evacuated, what pressure of oxygen will be attained when the temperature is finally cooled to 25°C? Use the preceding chemical equation and ignore the volume of solid product.
