Question

calculate the no.of atoms in 0.26 mole molecules of sulphur. S8

Answer 1

 multiply that by Avogadro's number to get the number of molecules in 8 grams. 0.0312moles x 6.022 x10^23 molecules per mole = 1.878864x10^22. Your question, though, was how many atoms, so you have to multiply that number which is how many molecules by 8 atoms per molecule of sulphur.

Answer 2

Take it always easy brother
No. of atom in a given mole of molecules is given by-
=>>N = No. of atoms in molecule × n × NA
answer will be 8×0.26×NA =2.08NA
Hope this will help you too
Have a great day my friend
