How many sulphur atoms are present in each of the following quantities
(i) 4.5 mole of S
(ii) 6 mole of S8 ?
(i) 1 mole of S = 6.023 x 1023 atoms of sulphur
4.5 mole of S = 4.5 x 6.023 x 1023 atoms of sulphur
= 2.71 x 1024 atoms of sulphur
(ii) 1 mole of S8 = 6.023 x 1023 molecules of S8
= 8 x 6.023 x 1023 atoms of sulphur
6 mole of S8 = 6 x 8 x 6.023 x 1023 atoms of sulphur
= 2.89 x 1025 atoms of sulphur
