Question

What is difference between normality, molality,molarity

Answer 1

Answer:

Explanation:

Molarity(M) is defined as number of moles of solute present in one litre of solution

Normality(N) is defined as number of gram equivalents of solute present in one litre of solution

Molality(m)  is defined as no of moles of solute present in one kilogram of solvent

one important point for competitive exams is :

molality is the best method to calculate the concentration of solution because it does not depend on temperature
