Dear student

FC = V-N-B/2
where V = no of valence electron
N = No. of non bonding electrons
B = No. of electrons in covalent bond
Formal charge of N on  NO3- =0
Formal charge of O on NO3- = -1/3

Formula change is basically a change given to an atom, on assuming that the electrons in a chemical bond are shared equally between the atoms, neglecting theirrelative, EN.
FC=VN2B       (V=no. of valance electronN=No. of non bonding electronsB=No. of electrons in covalent bond)
FC on N in NO3=0
FC on O in NO3=31
