Chapter 2 Question 25 Parameterization Sodium metal reacts with molecular fluorine gas to form sodium fluoride. A closed container of volume 2.00 x 10 ml contains fluorine gas at 46.0 °C and 4.39 x 10 Torr. Then 7.24 g of solid sodium is introduced, and the reaction goes to completion. What is the final pressure (in Torr) of the temperature rises to 124.0 °C? Tom
