Answer:

Multiply #4*mol# by #"Avogadro's number....."#

Explanation:

Here we use #"Avogadro's number"# as we would any other collective number, a dozen, a gross, a 100, or 1000........except that #"Avogadro's number"# is unfeasibly large......and specifies #6.022xx10^23*mol^-1#.

And thus for #H_2S# we have #4*molxx6.022xx10^23*mol^-1# #=# #24xx10^23# molecules. Can you tell me how many sulfur, and how many hydrogen atoms you got in this molar quantity? I think you could be able to do so.
