There are two facts you should obtain to calculate the molar mass of a hydrated compound. Those are the molar mass, say 'M' and the number of hydration 'N'.
Then the molar mass of the compound can be obtained by M + 18N.
(The molar mass of a water molecule is 18 g/mol)
It's not too hard: take a sample of a hydrate and get a really accurate mass for it. Then, stick your sample in a test tube and heat it up until it changes color completely (usually it will turn white.) This means all the water of hydration (sometimes called water of crystallization) has vaporized. Now, get another good accurate mass for the anhydrate. Work out the ratio of masses, and do a little stoichiometry with the molar mass of water (18 grams/mole.) You should end up with a certain number of moles of water per moles of substance.
Copper(II) sulfate is an easy one to do. When you do all the math, you end up with a ratio of 5 moles of water to every 1 mole of anhydrate, so the formula for copper(II) sulfate hydrate works out to be: CuSO4-5H2O.
you determin by using the desity
you divide by one million.

because you can't eat all the hydrates
Yes, all hydrates lose water after heating.
True and False. Methane hydrates form mostly under permafrost and ice caps, but some form in the ocean.Methane hydrates are expensive to obtain.
there are none
There is no direct way that methane hydrates, which are deposited deep under the ocean floor, are a danger for boats.
no they are not
hydrates are mainly used in artificial radioactivity and ............
because you can't eat all the hydrates
Yes , it forms different hydrates .
Yes, all hydrates lose water after heating.
is the gas methae (hydrates)ba potetial energy source?
carbonhydrates

It re-hydrates them.
fack you
hydrates us.
