The answer to this question would be: its concentration is half that of the cl - ion.

When CaCl2 molecule dissolved, it will split into one Ca2 + ion and two Cl - ion. That means for every 1 CaCl2 there will be 3 ions formed. In this case, the amount of Ca2 + should be half of Cl - ion. An element with higher valence tends to have less atom in a molecule than an element with lesser valence electron.
