Answer:

1.772   x 10²⁴ atoms

Explanation:

Molar mass of sulphur (S8) = 8 x 32 = 256 g / mol

∴ No. of moles of S₈ = \frac{100}{ 256} = 0.39 mol

∴ No. of molecules = 0.39 x 6.022 x 10²³ =  2.34  x 10²³ molecules

 No. of S-atoms = 2.34  x 10²³ x 8 atoms

                             =  17.72   x 10²³ atoms

                             = 1.772   x 10²⁴ atoms
