A metal has an face-centered cubic (f. c. c.) Bravais lattice or A1 crystal structure. The
lattice constant is 0.38 nm (0.38 x 10-9 m) and the atomic weight of the atoms is 85
gram/mole. (12 points)
a) What is the density of this metal?
b) What is the distance between neighboring atoms?
c) The metal is cut so that the (111) is exposed on the surface. Draw the arrangement of
atoms you would see if you looked at this surface. Label the two directions in the (111) plane
