Hydration number of a crystal
Webcrystal, any solid material in which the component atoms are arranged in a definite pattern and whose surface regularity reflects its internal symmetry. The definition of a solid appears obvious; a solid is generally thought of as being hard and firm. Upon inspection, however, the definition becomes less straightforward. A cube of butter, for example, is hard after … Web30 apr. 2024 · Divide the number of moles of water lost by the number of moles of anhydrous salt to get the ratio of water molecules to formula units.
