Why, three moles of ions......

Explanation:

And in aqueous solution, one mole of #MgCl_2(s)# speciates to give three moles of ions....i.e.

#MgCl_2(s) stackrel(H_2O)rarrMg^(2+) + 2Cl^(-)#

And both magnesium and chloride occur as their aquated ions....and as written this is correctly described as a chemical reaction.
