Answer:

#"Number of sulfur atoms"# #=# #100xxN_A#...where...

Explanation:

#"Number of sulfur atoms"# #=# #100xxN_A#...where #N_A# #=# #"Avogadro's number"#, #6.022xx10^23*mol^-1#.

And thus #"Number of sulfur atoms"# #=# #100*molxxN_A# #=# #10^2*molxx6.022xx10^23*mol^-1=6.022xx10^25# #"sulfur atoms"#.

How many sulfur atoms in #100*mol# of #Na_2^(+)S_2O_3^(2-)#, #"sodium thiosulfate"#?
