Consider a cube of chromium 1.00 mm on side. The atomic weight of chromium is 52.0 g/mol and the atomic radius is .125 nm.

a. If the chromium cube at absolute zero temperature had a perfect BCC crystal structure, calculate the number of chromium atoms present in the cube.

b. If 1 electron volt (eV) is required to create a vacancy in chromium, calculate the temperature at which one in every million of the lattice sites is vacant.
