No. Of moles are 2
No.of atoms are 2×6.022×10^23
No.of atoms are 2×6.022×10^23
Its correct
It's not S but S8
Please recheck...
yes this is approximately right
plz tell me how
MM of S8 is 256 amu and not 32
plz give a detailed answer in any of my other non answered questions
So (mass given/molar mass) is 64/256 = 1/4
So number of moles can be found by mass given/molar mass formula, here mass given is 64 gms and molar mass is mass of a single atom into number of atoms, which is 32×8 (As it is S8) so these values can be taken...
Hope this helps
