What else can I help you with?
Do you include water of crystallisation when calculating molar mass?
Yes, you most certainly do. For example, CuSO4 has a molecular weight of 159.6g/mol, yet it's pentahydrate has a molecular weight of 249.684g/mol. If you didn't add in the pentahydrate. You'd have about 40% error in the molarity.
What is meant by water of crystallisation in a substance?
H
Is Na Cl anhydrous?
Yes. There is no water of crystallisation.
Which crystal does not contain water of crystallisation?
NaCl salt does not contain water of crystallization.
What is water of crystallisation?
The water of crystallization is a type of water contained in the molecular structure of a compound.
How can you separate the water from the salt of crystallisation?
This can be done by heating the salt.
What is the formula or calcium chloride?
CaCl2 , the anhydrous (no water of crystallisation) form. There are various hydrates.
What the molar mass of water?
The molar mass of water is 18 g/mol.
What is the general name given to crystals that have lost all their water of crystallisation?
de-watered crystals
Is crystallisation of water a chemical change?
No,it's a physical change Because there is no change in matter's composition.
What happened during crystallization process?
A soluble salt turns into the crystalline form, usually with its water of crystallisation
How do you find theoretical percent of water?
To find the theoretical percent of water in a compound, you need to determine the molar mass of the compound and the molar mass of water. Then, divide the molar mass of water by the molar mass of the compound and multiply by 100 to get the percentage.
