You know, I could replace #"moles"# by #"dozens"# here and get the right answer.

Explanation:

The mole is just another number, admittedly it is a very large number, #N_A=6.022xx10^23*mol^-1#. Let's do the problem by using #"dozens"#: #"1 dozen"="12 items of stuff"#.

#a.# #"6 dozen S atoms"# #-=# #"72 sulfur atoms"#

#b.# #"2 dozen"# #S_8# #"atoms"# #-=# #"192 sulfur atoms"#

#c.# #"5 dozen"# #SO_2# #"molecules"# #-=# #"60 sulfur atoms"# and #"120 oxygen atoms"#.

#d.# #"2 dozen"# #CO_2# #"molecules"# #-=# #"24 carbon atoms"# and #"48 oxygen atoms"#.

And the answer is clearly #b.# Are you following me?
