#NI_3# has over 96% iodine content by mass.

Explanation:

The molecular mass of #NI_3# is #394.72# #g*mol^-1#.

Thus, #%I# #=# #"Mass of iodine"/"Mass of nitrogen triiodide"xx100%# #=# #(3xx126.9*g*mol^-1)/(394.72*g*mol^-1)xx100%# #=# #??%#

This material is actually not too difficult to make. It is very SHOCK sensitive when dry, which of course is why it is not often made in undergraduate laboratories.
