  5. Problem CsCl has a structure with Cl- ions on the corners and a Cs+ ion in the center of the cube. The density of CsCl is 3.97 g/cm3. Find the length of the edge of the cube.

  6. Mass of unit cell: (132.9 + 35.5 g/mol)(1 CsCl / cell)(1 mol / NA) = 2.797 x 10-22 g / cell Volume of unit cell: V = Mass / Density = 2.797 x 10-22 / 3.97 = 70.4 x 10-24 cm3 Length = (Volume)1/3 = 4.13 x 10-8 cm = 4.13 Å
