[Co(NH3) 3Cl3]

Why is the charge of Cobalt +3 and not +2 in [Co(NH3) 3Cl3]?

The charge for Cobalt is +3 because there are three chlorines which all have a -1 charge and the three NH3 do not have a charge. Therefore, to balance the charge you would need Cobalt to have a +3 charge. I hope this helps!

Cobalt is 3+ because [Co(NH3)3Cl3] is neutral, NH3 is a neutral ligand, and Cl is an anionic ligand with a 1- charge (since there are three Cl, their overall charge contribution is 3-). Thus, the cobalt is 3+ so it can cancel out the charge contribution of the Cl. Hope this helps!
