The number of water molecules in a hydrate can be determined by Thermogravimetric analysis. In a laboratory, it can be done as follows.
- Take a hydrated salt sample of known mass, m1.
- Heat it in the presence of a dessicant to dehydrate it, measure the mass again. Let this mass be m2.
- Subtract m2 from m1. This is the mass of water present in the sample, m.
- Divide the factor m with molar mass of water i.e. 18.015 g.
- The factor given thus is the number of water molecules in the sample.
It should be kept in mind that this method is not as accurate as the termogravimetric analysis.

What is loss of water of crystallization?
Exactly what it says. Some compounds incorporate water molecules into their crystals. These water molecules are called "water of crystallization." Heating such crystals often drives off the water through evaporation, which is an example of the loss of water of crystallization.
What is the example of crystallization?
salt and water or also frozen water. In order though for a crystal to be created it must be supersaturated.sodium chloride is also an example of crystallization
What are the two ways minerals are formed?
In general, minerals can form in two ways: through the crystallization of melted materials, and through the crystallization of materials dissolved in water.
How do you separate common salt from the mixture of common salt and water?
By evaporation of the water and crystallization of the salt.
How 16H2O molecules are formed in aluminum sluphate?
These compounds are called hydrates; water is called water of crystallization.
What is water in a crystal that is an integral part of the crystal structure called?
water of crystallization or water of hydration or crystallization water
What is the chemical name for nH2O?

What is haydrated salts?
A hydrated salt contain water of crystallization.
How do you make a sentence with crystallization in the sentence?
crystallization usually takes a long time. Crystallization is the reason that water expands as it freezes.
