Graphite is a mineral with many technological uses and it is perhaps most familiar for its use in writing instruments. Graphene is a 1 atom thick layer of graphite with many interesting properties and uses. Suppose the thickness of graphene is 200 picometers: one picometer is one trillionth of a meter.

About how many times would you have to split a 1 mm thick sample of graphite in half in order to get a single layer of graphene?

Write and solve an equation to model the presented scenario. Write your answer exactly and rounded to the nearest hundredth. Show all work.
