Answer:

About #2.5" moles"#

Explanation:

#"Number of moles"# #=# #"Mass"/"Molar mass"#

#=# #(80*g)/(32.06*g*mol^-1)# #=# #??mol#

Note that sulfur likely exists in its elemental state as #S_8#. I am perfectly justified in treating sulfur as #S#. The number of #"sulfur atoms"# is the same in each case.
