As we know that graphite is the allotrope of carbon. Therefore molar mass of graphite = 12 g mol-1
​Number of atoms of graphite = Given mass / Molar mass x 6.022 x 1023
                                              = 10-18 g/12 g x 6.022 x 1023
                                              = 5.0 x 104 atoms
