Answer:
The number of waters of hydration determined will be too high and the mass of the anhydrate remaining will be reported as too low. We know dessicator is used to remove water from the sample under investigation (hydrous to anhydrous) chemicals such as Anhydrous CaCl2, silica gel. If a student forgot to place the heated sample in the dessicator while cooling, and some water was re-absorbed by the copper (II) chloride, then the number of waters of hydration determined be too high.
