Based on the category, this answer will refer to sodium chloride, NaCl. Gfm is gram formula mass and is the same thing as molar mass. To find the gram formula mass of NaCl, you add the gram atomic masses (gam) from the Periodic Table (atomic weights) of the sodium and chlorine atoms in one formula unit.
gam Na = 22.99g/mol
gam Cl = 35.45g/mol
Ggm of NaCl = 22.99g/mol + 35.45g/mol = 58.44g/mol

What is an hydrous salt?
An hydrous salt is a salt that contains water molecules within its crystal structure. These water molecules are known as "water of hydration" and can be removed through heating to form an anhydrous salt.
What is the term a hydrate with the water heated off?
Anhydrous is the term for a hydrate with water heated off. when a hydrated salt is heated, it loses water of crystallization leaving an anhydrous salt.
Suppose the original sample is unknowingly contaminated with a second anhydrous salt will the reported percent water in the hydrated salt be too high too low or unaffected by its presence?
If the original sample is unknowingly contaminated with a second anhydrous salt, the reported percent water in the hydrated salt will be too low. This is because the presence of the anhydrous salt will increase the overall weight of the sample without contributing to the water content calculation, leading to a lower reported percentage of water in the hydrated salt.
Is barium iodide a salt?
Yes, Im taking chemistry at the community college. Barium dichloride is an anhydrous salt.
Why is a beaker placed over anhydrous salt as it cool?
A beaker is placed over anhydrous salt as it cools to prevent moisture from the air from coming into contact with the salt. Anhydrous salts are hygroscopic, meaning they readily absorb water vapor, which can lead to the formation of hydrates or alter their properties. The beaker acts as a barrier, ensuring that the salt remains dry and maintains its intended state. This practice is particularly important in laboratory settings where precise chemical properties are required.
What is an example of a anhydrous salt?
For example uranyl nitrate may exist as an anhydrous compound.
What is the chemical formula for anhydrous salt?
The chemical formula for anhydrous salt is the same as the formula for the hydrated version of the salt, but it does not include water molecules. For example, anhydrous copper sulfate is CuSO4, while hydrated copper sulfate is CuSO4·5H2O.
Is aluminum chloride anhydrous a salt?
Yes, aluminium chloride is a salt.
What happens when a hydrate heated?
When a hydrate is heated, the water, h20 is evaporated, leaving only the anhydrous salt. If you add water to a anhydrous salt, it will transition back into a hydrate.
What color is associated with the hydrated form of cobalt chloride?
cobalt chlorideCompound that exists in two forms: the hydrated salt (CoCl2.6H2O), which is pink, and the anhydrous salt, which is blue. The anhydrous form is used as an indicator because it turns pink if water is present. When the hydrated salt is gently heated the blue anhydrous salt is reformedcobalt chlorideCompound that exists in two forms: the hydrated salt (CoCl2.6H2O), which is pink, and the anhydrous salt, which is blue. The anhydrous form is used as an indicator because it turns pink if water is present. When the hydrated salt is gently heated the blue anhydrous salt is reformedCobalt chloride in simple terms.When the cobalt chloride has no water (ANHYDROUS) it is BLUE. when water is present then the anhydrous cobalt chloride becomes HYDRATED cobalt chloride and it is PINK.
What is an anhydride salt?
If you think to an anhydrous salt this is a salt which doesn't contain any water in the crystalline structure.
What is an hydrous salt?
An hydrous salt is a salt that contains water molecules within its crystal structure. These water molecules are known as "water of hydration" and can be removed through heating to form an anhydrous salt.
How can you obtain hydrated salt?
To obtain hydrated salt, you can dissolve an anhydrous salt in water and then evaporate the water to grow hydrated crystals. Alternatively, you can mix the anhydrous salt with a calculated amount of water to form a solution with a specific hydration level.
How are anhydrous salts prepared?
Anhydrous salts prepared by evaporating the water contained in a hydrated salt. However, anhydrous salts are non-electrolytes, meaning they can't pass an electric current.
What is the term a hydrate with the water heated off?
