The Russian Mir space station used a chemical oxygen generator system to make oxygen for the crew. The system ignited a tube of solid lithium perchlorate (LiClO4) to make oxygen and lithium chloride (LiCl): LiClO4(s)→2O2(g)+LiCl(s)

If you have 500 g of LiClO4, then how many liters of oxygen will the system make at the station s standard operating conditions, a pressure of 101.5 kPa and a temperature of 21 C? (Show the steps involved in your work.)
