(a) The density of diamond [Figure 12.30(a)] is 3.5 g/cm3 and that of graphite [Figure 12.30(b)] is Based on the structure of buckminsterfullerene (Figure 12.47), what would you expect its density to be relative to these other forms of carbon?
(b) X-ray diffraction studies of buckminsterfullerene show that it has a face-centered cubic lattice of C60 molecules. The length of an edge of the unit cell is 14.2 Å. Calculate the density of buckminsterfullerene?
