Answer 3

hint:
1) in Na2PFO3 molecule, there are:
3 atoms of oxygen, 1 atom of fluorine, 1 atom of phosphorus, and 2 atoms of sodium, in total 7 atoms

2) In H2SO4 molecule, there are 4 atoms of oxygen, 1 atom of sulfur, and 2 atoms of hydrogen, so 7 atoms in total

3) in Ni(NO3)2 molecule, there are 6 atoms of oxygen, 2 atoms of nitrogen, and 1 atom of nickel, so 9 atoms in total

4) in NbCl5 molecule, there are 5 atoms of chlorine and 1 atom of niobium, so 6 atoms in total

Answer 4

the answer is third one
