4 moles of Aluminum

Explanation:

If we assume that we are creating Aluminum Chloride from the
metal-acid reaction between Aluminum and hydrochloric acid we can begin with the balanced chemical reaction below.

#2Al + 6HCl -> 2AlCl_3 + 3H_2#

We can use the mole ratio #(2 mol Al)/(2 mol AlCl_3)#

The stoichiometry equation becomes

#4 mol AlCl_3 (2 mol Al)/(2 mol AlCl_3)#

#4 cancel(mol AlCl_3) (cancel2 mol Al)/(cancel2 cancel(mol AlCl_3))#

#= 4 mol Al#
