Calcium nitrate has 9 atoms.
9 atoms = 1 Copper + 2 Nitrogen + 6 Oxygen
Nine atoms represent the empirical formula of ammonium nitrate. Namely, 2 nitrogen atoms, 3 oxygen atoms and 4 hydrogen atoms.
The formula unit of aluminum nitrate is Al(NO3)3. This shows that the formula unit contains 1 aluminum atom, 3 nitrogen atoms, and 9 oxygen atoms for a total of 13 atoms.

Calcium nitrate has 9 atoms.
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
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
Magnesium nitrate is MgNO3 and there are one magnesium atom one nitrogen atom three oxygen atoms no potassium atoms
9 atoms = 1 Copper + 2 Nitrogen + 6 Oxygen
Calcium nitrate has 9 atoms.
Nine atoms represent the empirical formula of ammonium nitrate. Namely, 2 nitrogen atoms, 3 oxygen atoms and 4 hydrogen atoms.
There are 5 atoms in silver nitrate (1 silver, 1 nitrogen and 3 oxygens).
Ca (NO3)2 So the number of Ca atoms will just be Avogadro's constant, L
9 atoms Here is the formula for ammonium nitrate. NH4NO3 This shows there are two nitrogen atoms, 4 hydrogen, and 3 oxygen. So 1 (nitrogen) + 1(nitrogen) + 4(hydrogen) + 3(oxygen) = 9 atoms

The formula unit for calcium nitride is Ca3N2. That would be 3 atoms of calcium and 2 atoms of nitrogen, for a total of 5 atoms in a formula unit.
