Some ionic compounds exist in crystalline form with a certain number of water molecules associated with the ions. Such compounds are called hydrates. For example, calcium sulfate can exist with either one-half water molecule per formula unit, written as CaSO₄ · ½H₂O, or two water molecules per formula unit, written as CaSO₄ · 2H₂O. What is the percentage water (by mass) for each compound?
