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, platinum has a density of 21.45 g/cm3 and a unit cell side length (a) of 3.93 Å. (1 Å = 1. 10-8cm).

(a) How many platinum atoms are in 1 cm3?
(b) How many unit cells are in 1 cm3?
(c) How many platinum atoms are there per unit cell?
