I'm trying to find out what is the highest amount of hydration an element or compound can have and still be a solid or powder/dry - ex- MgSO4 .7H2O.
Also is there any way to increase the hydrate level of compounds or "prod" them into giving up their water to another compound? (like adding another
compound to MgSO4 heptahydrate that would take some/all of the water from it).
I'm very interested in an inexpensive compound that can be purchased in bulk so I can do some experimenting with it.
Also, if calculating the atomic weight of a hydrate is it simply the (weight of the element) + (N * weight of water)?

How about super absorbent polymers?

Many can absorb many times their weight in water and still remain "solid."
Yes, the molar mass of a hydrate is: anhydrous g/mol + nH2O g/mol. The mole fraction is thus anhydrous/hydrate.

On that note, sodium polyacrylate / 'fake snow'?
