Question

Calculate the number of molecules of Sulphur (S8) present in 16 gms of solid sulphur

Answer 1

atomic mass of S8 is 32×8 gms
..you have given me 16gms
therefore 1/16 moles of S is given!
hence number of molecules of S8 = 1/16 × Na ..
where Na is Avogadro number.
So answer comes to be = 3.7 × 10^22 (approx)

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)
