Graphene has a C-C bond length of 1.42 AÌŠ.
(a) Suppose you deposit a single layer of graphene around theentire earth, which has a diameter of 1.27 × 10^7 m. What would bethe mass of this graphene layer?
(b) If the graphite in a wooden pencil has a mass of 60 g, whatsurface area could it cover, if it would be exfoliated as a singlelayer of graphene?
