hydrated magnesium 2

Formula of a Hydrate (Anhydrous Solid ⋅ xH2O Anhydrous Solid ⋅ x H 2 O) The formula of a hydrate can be determined by dehydrating a known mass of the hydrate, then comparing the masses of the original hydrate and the resulting anhydrous solid. The mass of water evaporated is obtained by subtracting the mass of the anhydrous solid from the ...
