Expert Answer:

Dear Student
 
Normality-- Normality, N, is similar to molarity, moles of solute per liter of solution. However, instead of the entire solute, the normality is based on the number of moles of the active part of the solute, called a chemical equivalent.
 
Normality= equivalents/volume(L)
 
Formality, F, is the number of formula weight units of solute per liter of solution. Remember that one mole of a compound has a mass equal to the formula weight in grams.
 
 
We hope that clarifies your query.
