Question

calculate the number of molecules of sulphur S8 present in 16g of solid Sulphur​

Answer 1

Molecular mass of sulphur = 32 x 8

= 256g

One mole of sulphur molecule = 256g of sulphur.

16g of sulphur will contain 1/256 x 16 moles of sulphur molecule.

= 0.0625 moles of sulphur molecule.

1 mole of S molecule = 6.022 x 10^23

0.0625 mole of S molecule = 6.022 x 10^23 x 0.0625

= 3.76375 x 10^22 sulphur molecule.

Answer 2

$<b>$☺ Hello mate__ ❤

◾◾here is your answer.

1 mole of solid sulphur (S8)

= 8 × 32g

= 256g

i.e., 256g of solid sulphur contains

= 6.022 × 10^23 molecules

Then, 16g of solid sulpur contains

(6.022×10^23 /256 )16 molecules

= 3.76 × 10^22 molecules (approx)
