Question

calculate the numbers of molecules of sulphur (S8) present in 16 gram of solid Sulphur​

Answer 1

The molar mass of S8 = 256 gmol-1

i.e., 256 g of solid sulphur contains = 6.022 x 1023 molecules

Then, 16 g of solid sulphur contains =6.022 x 1023 / 256 = 16 molecules

= 3.76375 x 1022 molecules

Therefore, 16 g of S8 contains 3.76 x 1022 molecules.

Answer 2

We can see from the above discussion that it contains 3.764×1022 molecules. Therefore, the answer is will be – the number of molecules of sulphur (S8) present in 16g of solid sulphur is 3.764×1022.
