full solution
When an ionic compound dissolves in water, it undergoes dissociation into its constituent ions. The total moles of ions released is determined by adding up the moles of each ion generated during this dissociation process. In the case of (a) disodium hydrogen phosphate (Na?HPO?), it dissociates into two sodium ions and one hydrogen phosphate ion. For (b) copper(II) sulfate pentahydrate (CuSO? · 5H?O), it dissociates into one copper ion and one sulfate ion. In (c), nickel(II) chloride (NiCl?) diss
