Are the twelve waters of hydration used to calculate the theoretical yield of the alum?

Yes, 12H2O do count toward theoretical yield of alum, since it is an integral part of alum formula. Otherwise it would be just K-Al double sulfate, with different structure.

There are four water molecules bound to Sodium Chromate
What is primary standard solution?

How are aromatic waters preserved?
Aromatic waters are preserved by placing them in airtight and light-resistant containers.
Is coffee good for hydration?
Not really, Waters the BEST
What is a turqouise made of?
A phosphate of copper and aluminium with some waters of hydration.
How are hydrated salts different from anhydrous salts?
A hydrated salt has a number of waters of hydration combined to each molecule of salt whereas an anhydrous salt is one that has had its waters of hydration removed. An example of a hydrated salt is nickel sulfate hexahydrate, NiSO4·6H2O. The waters of hydration can be removed by a simple heating, resulting in NiSO4(s) + 6H2O(g).
What does NaH2PO4.2H2O mean?
This is the formula for disodium hydrogen phosphate dodecahydrate.
Why chemicals are hygroscopic in nature?
Not all of them are. Those that do have that property have it because it's energetically favorable for them to either dissolve or have waters of hydration, which is unfortunately a kind of fancy scientific way of saying "it happens because it happens."
Why Potassium dichromate is used for calibrate the control of absorbance of UV spectrophotometer?
Potassium dichromate is used as the primary standard for UV spectrophotometry because of its properties. It is pure, stable, has no waters of hydration, and has a high molar mass.

Does moon have water and air on it?
Scientists believe the Moon may have water in the form of waters of hydration inside rocks and frozen into the surface. However, it has no standing liquid water, and while it does technically have an atmosphere it's extremely thin and would be considered an "ultra high vacuum" in an Earth laboratory.
Are all the compounds of copper plus 2 blue?
Not necessarily. They might be blue, green, or essentially white depending on how many waters of hydration are associated with the copper (II) ion. It's very easy to see this if you just take some copper (II) sulfate pentahydrate (blue vitriol) in a test tube and heat it; as the waters of hydration are driven off, the crystals turn white (some people call it a very light green; it looks white to me). When the crystals are allowed to cool they will absorb water from the air and eventually turn blue again. Aqueous solutions of copper (II) compounds are blue, as far as I know; at least I can't think of any counterexamples.
Why aromatic waters also known as medicated waters?
Aromatic waters are waters that are infused with essential oils. The essential oils that are infused into these waters have medicinal value.
