1. Find the molar mass of the hydrate (Calcium Chloride Dihydrate).
Find the molar mass of water and the anhydrate (anhydrate + water = hydrate); add the molar mass values of each to find the molar mass of the hydrate.
Molar Mass CaCl2: 110.98g
+ Molar Mass H2O: 36.04g*
Molar Mass CaCl2 * 2H2O: 147.01g
Finding Molar Mass
# atoms element A * Atomic Mass element A = Mass A
# atoms element B * atomic mass element B = Mass B
... etc.
Add up all the mass values and you have the value for molar mass. Do this for both the anhydrate and the water molecules. Add these values together to find the molar mass of the hydrate.
Molar Mass Anhydrate + Molar Mass Water Molecules* = Molar Mass Hydrate
* Tip: the molar mass of water for all hydrate calculations is 18.02g x number of water molecules. This number may be useful to remember on the day of the test or while doing practice problems.*
2. Calculate the percentage of water in hydrate.
Divide the molar mass of water by the molar mass of the hydrate, and multiply result by 100%.
36.04g
147.01g x 100%
Percent water in hydrate is 24.52%.
A hydration equation gives information regarding the reactants and products formed when a substance dissolves in water. Since a hydration reaction takes place in water, the solvent water can be indicated above the arrow. For example, the hydration equation for a strong electrolyte, such as , can also be written as Similarly, the hydration equation for a weak electrolyte, such as , and a nonelectrolyte, such as , can be written as
Hydration is having water, dehydration is having less water than the minum something needs to work.
Hydration means that u are hydrated, in other words, it's like drinking water or liquid
The hydration of an ion is always negative. This is because ion and water attractions are only formed when the ion is surrounded by water, deeming it negatively charged.

how is water hydration related to measurement
It depends on what the solvent is. If it is water, then it is called hydration. If the solvent is not water, then it cannot be called hydration.
Hydration is incredibly important because the body is nearly 60% water. Without proper hydration, the muscles and organs will begin to shut down. One factor of hydration is not drinking enough water, another is sun exposure.

hydrolisis is the chemical breakdown of rocks as they react with water where as hydration is the breakdown of rocks as they absorb water.

Hydration is a chemical reaction. It involves the addition of water to another substance.
Beats me.
Drink water.
Hydration is very important because adequate hydration is essential for health and wellbeing. Every cell in the body needs water. Hydration is the mainstay of most basic physiological functions, such as regulating blood pressure and body temperature, hydration and digestion.
