Answer:

#9.6xx10^-3# total moles of ions.

Explanation:

A sodium iodide unit is conceived to derive from one #Na^+# and one #I^-#. Because matter is electrically neutral these combine in a 1:1 fashion.

You specified #4.80xx10^-3# #mol# of #NaI#. In this molar quantity there are #4.80xx10^-3# #mol# of #Na^+# ions, and #4.80xx10^-3# #mol# of #I^-#; i.e. #9.6xx10^-3# of individual ions.
