    Calcium carbonate nonahydrate is a hydrous compound of calcium carbonate \(CaCO_3\) and water \(H_2O\). The number of \(H_2O\) molecules is denoted by a Greek prefix in the name of the hydrate; nona- means nine. This means we can write our compound as \(CaCO_3\cdot 9H_2O\). http://en.wikipedia.org/wiki/Hydrate#Inorganic_chemistry
