How many atoms of carbon graphite in pencil mark?

A pencil mark primarily consists of graphite, which is made up of carbon atoms. In a typical pencil mark, there are approximately 10^19 to 10^20 carbon atoms in a single mark, depending on its size and thickness. This vast number reflects the microscopic scale of atoms and the relatively small quantity of graphite used in a pencil mark.
