It is often possible to change a hydrate into an anhydrous compound by heating it to drive off the water (dehydration). A 45.21 gram sample of a hydrate of Ca(NO3)2 was heated thoroughly in a porcelain crucible, until its weight remained constant. After heating, 31.41 grams of the anhydrous compound remained. What is the formula of the hydrate?
