Cu(NO3)2 has 9 atoms 1 Cu atom 2 N atoms 6 O atoms
There are 11 atoms in one formula unit of Cu(NO3)2: one copper atom (Cu), two nitrogen atoms (N), six oxygen atoms (O), and two nitrogen atoms (N) from the nitrate (NO3) group.
Copper nitrate molecule contain nine atoms.
There are a total of 27 atoms in 3Cu(NO3)2. This includes 3 copper (Cu) atoms, 6 nitrogen (N) atoms, and 18 oxygen (O) atoms.
The compound copper nitrate has Cu(NO3)2 for a chemical formula. In that formula, we see that there is an NO3 radical present, and that there are 3 atoms of oxygen in that radical (the sub 3 after the O). But there are 2 of those NO3 radicals (the sub 2 outside of the parens) present in this compound. That means that there are 3 x 2 oxygen atoms in a molecule of copper nitrate, or 6 atoms of oxygen in Cu(NO3)2.
Copper nitrate has six atoms of oxygen.

It generally refers to Copper(II) nitrate: Cu(NO3)2
Cu(NO3)2 and CuNO3 cupric (Cu-II) and cuprous (Cu-I) nitrate
9 atoms = 1 Copper + 2 Nitrogen + 6 Oxygen
Copper(II) nitrate has six oxygen atoms.
