During your experiment, you are drive water from the hydrate M x X y ⋅zH 2 O . You subsequently determine that your hydrate has four molecules of waters associated with each formula unit. However, the bottle the hydrate came from indicated a formula with only six molecules of water. What went "wrong" in your experiment?

The bottle was previously opeedn, thus altering the water content. This is because hydrates do not keep their stoichiometric ratio of cations and anions to water molecules. Hope this helps.
