1. Find the molar mass of the hydrate.
Find the molar mass of the water molecules (18.01528 x # water molecules) and of the anhydrate; add the values together to find the molar mass of the hydrate.
Molar Mass Water + Molar Mass Anhydrate = Molar Mass Hydrate
2. Find the percent of water in hydrate.
Divide the molar mass of water by the molar mass of hydrate; multiply by 100%.
- Mass water
Mass hydrate x 100%

Would CoCl2 6H2O cause a chemical reaction?
When CoCl2·6H2O is heated, the water molecules are driven off, leaving anhydrous CoCl2. This is a physical change, not a chemical reaction. However, the anhydrous CoCl2 can undergo chemical reactions depending on the conditions and other reactants present.
How many grams of CoCl2 6H2O are needed to prepare 50.0ml of a 0.30M CoCl2 solution?
To determine the mass of CoCl2 6H2O to prepare a 0.30M solution in 50.0ml, we first calculate the molar mass of CoCl2 6H2O. The molar mass is 237.93 g/mol, so for a 0.30M solution in 50.0ml, we can use the formula: mass = molarity x volume (L) x molar mass. Therefore, the mass of CoCl2 6H2O needed is 3.57 grams.
How many grams of CoCl2 6H2O must you measure out in a container to have exactly Avogadros number of particles?
To have Avogadro's number of particles of CoCl2 6H2O, you would need to measure out 1 mole of the compound. This is equivalent to the molar mass of CoCl2 6H2O in grams, which is approximately 237.93 grams.
What color is CoCl2-6H2O-ethanol?
The color of CoCl2-6H2O in ethanol solution is typically pink or rose-red. This color arises from the presence of the hydrated cobalt(II) ions in the complex.
What are the colors of CoCl2 and CoCl26H20?
Blue, and Pink. Its a chemistry experiment.When hydrated the cobalt cloride is pink. When it dries it's blue.
When colbalt chloride unties with water to form hexahydrate its formula is written CoCL2 6H2O?
Yes, CoCl2 * 6H2O is the hexahydrate of the an hydrate CoCl2.

Whatcolor is change by heat CoCl2-6H2O?
The color of hydrated cobalt chloride (CoCl2•6H2O) changes from blue to pink when heated due to the dehydration of the compound. Upon heating, the water molecules are removed, leaving behind anhydrous cobalt chloride which is pink in color.
In the presence of water what happens to anhydrous cobalt chloride?
Anhydrous cobalt chloride will absorb water and form hydrated cobalt chloride. This process is reversible, with the hydrated cobalt chloride releasing water vapor to revert back to anhydrous cobalt chloride when heated.
How do you dehydrate CoCl2 6H20?
To dehydrate cobalt(II) chloride hexahydrate (CoCl2·6H2O), you can gently heat the compound in a dry oven or on a hot plate at a temperature around 100-120°C. This process drives off the water molecules, resulting in anhydrous CoCl2. It's important to monitor the temperature to avoid overheating, which can lead to decomposition. Always handle with care, as cobalt compounds can be hazardous.
What is the name for 6H2O?
The chemical name is usually "water" for H2O regardless of how many there are. In naming a hydrate such as CuSO4.5H2O we first name the compound before the "dot". Here it is "copper(II) sulfate". Then use the prefix for the number of water molecules attached. Here it is "penta" for five. The "dot" tells us that it is a hydrate. The name of CuSO4.5H2O would be "copper(II) sulfate pentahydrate".
When a sample of 20.0 g of CoCl2 - 6H2O is dried in an oven until dry CoCl2 is obtained what is the mass of dry cobalt chloride?
Equation:CoCl2.6H2O + heat --> CoCl2 + 6H2OYou have the mass of CoCl2.6H2O, which is 20g.You know the Mr of CoCl2.6H2O as well:58.93 + 35.5(2) + 6(18)= 237.93gmol-1 (The 18= H2O)You know the formula to calculate the no. of moles:n=mass/Mr, therefore n= 20/237.933 = 0.0841 molesThe ratio of CoCl2.6H2O: CoCl2 is 1:1, therefore CoCl2 has the same number of moles as does CoCl2.6H2O.So you want the mass of CoCl2? Well you havethe the Mr of it and now you have the no. of moles.Mr of CoCl2:58.93 + 35.5(2)= 129.93 (Or you could simply do 237.93 - 6(18) )Since n=mass/Mr you simply rearrange to get mass by itself. Which is:mass= n x MrTherefore the mass ofCoCl2ismass = 0.0841 x 129.93 = 10.92g (Answer)Daniel Hajsadr
What is the chemical symbol for Methane Hydrate?
Methane Hydrate is methane gas which has been frozen into water ice. Since it is a mixture of substances, and not an individual chemical, it does not have a chemical symbol. However, it can be represented by the chemical symbols of the compounds which make it up - Water, which is H2O, and Methane, which is CH4.
