1 mole of S8 molecules = 6.023 x 1023 molecules of S8
Therefore 0.1 mole of S8 molecule  = 0.1 x 6.023 x 1023  molecules of S8
                                                 = 6.023 x 1022 molecules of S8
Also,                 1 molecules of S8 =  8  atoms of sulphur
                     6.023 x 1022 molecules of S8 = 8 x 6.023 x 1022   atoms of sulphur

                                                               = 4.82 x 1023  atoms of sulphur
