It is often possible to change a hydrate into an anhydrous compound by heating it to drive off the water (dehydration). A 39.45 gram sample of a hydrate of BaI2 was heated thoroughly in a porcelain crucible, until its weight remained constant. After heating, 30.91 grams of the anhydrous compound remained. What is the formula of the hydrate?
It is often possible to change a hydrate into an anhydrous compound by heating it to drive off the water (dehydration). A 30.74 gram sample of a hydrate of Ba(ClO4)2 was heated thoroughly in a porcelain crucible, until its weight remained constant. After heating, 26.49 grams of the anhydrous compound remained. What is the formula of the hydrate? Use a period instead of a dot in the formula of the hydrate.

It is often possible to change a hydrate into an anhydrous compound by heating it to drive off the water (dehydration). Write an equation that shows the dehydration of manganese(II) sulfate tetrahydrate. Use an asterisk to enter the dot.
A hydrate of Cobalt(ii)Chloride had mass of 166.04g before heating. After heating, the anhydrous CoCl2 weighed 130.9g. - what is the mass of the water that was driven off? - how many moles of water were driven off? - how many moles of anhydrous CoCl2 remain? - what is the hydration number (moles of water per mole compound)?
A sample of hydrate was heated thoroughly. How many waters of hydration are there if the anhydrous salt had a dry mass of 12 grams and a molar mass of 185 g/mol? The mass of water evaporated from the hydrate was 5.0 g.
