Answer:

1 mol aluminium chloride #AlCl_3# delivers 3 mol of #Cl^-# ions.

Explanation:

So #4.50# mol #AlCl_3harr3xx4.50=13.50# mol #Cl^-#

1 mol contains #~~6.02xx10^23# particles, so the answer is:

#n_(Cl^-)=13.50xx6.02xx10^23=81.27xx10^23~~8.13xx10^24#

(rounded to 3 significant digit because of the #4.50#)
