What is the number of atoms in calcium nitrate?

Calcium ions have a charge of +2 and nitrate ions (NO3) have a charge of -1. Because compounds are neutral, you need two nitrate ions to cancel out one calcium ion. Thus the formula for calcium nitrate is Ca(NO3)2. Nitrate has four atoms (one nitrogen and three oxygen). But there are two nitrate ions, so that makes eight atoms. Then you add on the one calcium atom for a total of nineatoms.

What are identical molecules?

Molecules are put together from atoms. If you have the same atoms, such as, let us say, one carbon and four hydrogen, and you put them together in the same way - in this case, with the carbon in the center and the hydrogen atoms symmetrically distributed around it - then the molecules are identical.
