We take the number if valence electrons in each of the atom and draws it to complete the octet.the nitrogen carries one negative charge making it having 5+1=6 Valene electrons .thus the structure becomes
O = N - O

The C-H and C-F bonds are polar and so the electron density will be shifted towards carbon in the C-H bonds and towards fluorine in the C-F bonds. Directing orbitals with more s character towards the hydrogens is stabilizing, while directing orbitals of less s character towards the fluorine is destabilizing but to a lesser extent.

Normality is defined as number of grand equivalent of solute dissolved per litre of solution . the equivalent mass required for it is defined as molecular mass divided by acidity/basicity of salt/ valence electrons/ electrons list or gained in redox rxn depending upon the type for which we are finding equivalent mass.
