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?

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
