How do you find the number of molecules of water in a hydrate?
Divide the mass of the water lost by the mass of hydrate and multiply by 100. The theoretical (actual) percent hydration (percent water) can be calculated from the formula of the hydrate by dividing the mass of water in one mole of the hydrate by the molar mass of the hydrate and multiplying by 100.

What is hydrate formation?
Hydrate Formation Hydrates are formed when water and light end natural gases come into contact at certain temperature and pressure conditions. These gas hydrates are crystals formed by water with natural gases and associated liquids, in a ratio 85 \% mole water to 15 \% hydrocarbons.
What is hydrated salt Class 10?
The salts which contain water of crystallisation are called hydrated salts. The salts which contain water of crystallisation are called hydrated salts.
What determines the formula of a hydrate?
Determining the Formula of a Hydrate A hydrate is an ionic compound that has a definite amount of water molecules attached to its crystalline structure. The ratio of water mol ecules to the anhydrous salt is constant. Many compounds exist as hydrates.
