Chapter 11, Problem 11.148(choose chapter or problem)
An alkali metal in the form of a cube of edge length 0.171 cm is vaporized in a 0.843-L container at 1235 K. The vapor pressure is 19.2 mmHg. Identify the metal by calculating the atomic radius in pico meters and the density. (Hint: You need to consult Figures 8.5, 11.22, 11.29, and a chemistry handbook.)
