What is the correct chemical formula for the hydrated crystal MnNO34 xH2O if analysis shows 511 g of MnNO34 and 334 g of H2O?
Calculate in two steps:
- Mn(NO3)4 : M = 25 + 4*(14 + 3*16) = 303 g/mol --> 511g / 303(g/mol) = 1.686 mol Mn(NO3)4 in total
- H2O M=18 g/mol -> 334g / 18(g/mol) = 18.55mol H2O in the same total amount (845 g) Mn(NO3)4.(H2O)x
x = 18.55 / 1.686 = 11
Control:
In total there is 1.686 (mol Mn(NO3)4.(H2O)11) * [303(g/mol) + 11*18(g/mol)] = 1.686*[303+198] = 844.7 gram Mn(NO3)4.(H2O)11
which,when rounded, is close enough to 845 (= 511+334) for the 3-digit accuracy.

Is NH4H2PO4 a hydraited crystal?
No, NH4H2PO4 is not a hydrated crystal. It is a salt composed of ammonium, hydrogen, phosphorus, and oxygen ions. It does not contain water molecules in its chemical structure.
How could you tell when a hydrated crystal is dry?
You can tell a hydrated crystal is dry by conducting a weight measurement before and after drying. A decrease in weight indicates that water has been removed. Additionally, the crystal may appear opaque or have a different color when hydrated, which can change back to its original appearance when dry.
Can a crystal cause a chemical change?
Yes,when you dissolve the crystal, because you are changing a crystal into water and therefore the crystal is goneRead more: Does_dissolving_a_crystal_cause_a_chemical_change

What is the chemical equation for hydrated copper sulphate?
The chemical equation for hydrated copper sulfate is CuSO4 • 5H2O. This indicates that each copper sulfate molecule is associated with 5 water molecules in its crystal structure. When heated, these water molecules are driven off, leaving anhydrous copper sulfate (CuSO4).
