Answer:

#+3#

Explanation:

In this compound, #CrCl_3#, it has a net charge of #0#.

Chlorine is more electronegative than chromium, and so it will possess its usual state of #-1#. There are three chlorine atoms in total, and so their total charge will be #-1*3=-3#.

Let #x# be the oxidation number of chromium. Then we have,

#x-3=0#

#x=3#

And so, chromium would have an oxidation state of #+3#.
