Lithium metal reacts with molecular oxygen gas to form lithium oxide. A closed container of volume 8.00 x 103 mL contains oxygen gas at 99.8 °C and 2.12 x 103 Torr. Then 11.5 g of solid lithium is introduced, and the reaction goes to completion. What is the final pressure (in Torr) if the temperature rises to 168.1 °C?
