Assume that the ionic compound CaCl2, separates completely into Ca and Cl ions when it dissolves in water. How many moles of each ion are present in the solution???
It all depends upon how many grams CaCl2 you dumped into the solution doesn't it? Certainly.
1 mol CaCl2 gives you 1 mol Ca ions and 2 mols Cl ions.
