Many metals pack in cubic unit cells. The density of a metal and length of the unit cell can be used to determine the type for packing. For example, sodium has a density of 0.968 g/cm3 and a unit cell side length a of 4.29 Å. (1 Å = 1. 10-8 cm.)
(a) How many sodium atoms are in exactly 1 cm3?
atoms

(b) How many unit cells are in exactly 1 cm3?


(c) How many sodium atoms are there per unit cell?
atom(s)

(d) The atoms/unit cell suggests that sodium packs as a unit cell.
