The formula for calcium nitrate is Ca(NO3)2
Hence there are two nitrogen (N) and 2 x 3 = 6 oxygens.
The bracketed moiety of nitrate followed by the '2', indicates that there are two(2) nitrate anions present.
More lengthily we could write it as O3N-Ca-NO3 , but this is very awkward, so chemists use brackets instead.
However, if it is a single element, then brackets are not used, e.g. calcium chloride CaCl2

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.
How many atoms are in CaS?
Calcium nitrate has 9 atoms.

How many atoms does Calcium Nitrate have?
6,022 x 1023 atoms/mole. Calcium nitrate = Ca(NO3)2 .There are 1 mole of calcium making 6,022 x 1023 atoms of calcium.There are 2 moles of nitrate-ions and each nitrate-ion is made up of 1 mole nitrogen, and 3 moles of oxygen. Thath means that the nitrate ion in calcium nitrate has 6 moles oxygen and 2 moles of nitrate:Atoms of nitrogen: 6,022 x 1023 moles-1 x 2 moles = 1,2044 x 1024 atomsAtoms of oxygen: 6,022 x 1023 moles-1 x 6 moles = 3,6132 x 1024 atoms
