MOLARITY AND NORMALITY FORMULAS

Define mole and the concept of molarity and normality:

  • The mole is a unit used in chemistry to measure the amount of a substance. 
  • One mole of a substance contains Avogadro's number of particles, which is approximately 6.02 x 10^23. 

  • Molarity is a unit of concentration that is defined as the number of moles of solute per liter of solution. 
  • It is commonly abbreviated as M and is expressed in moles per liter (mol/L). 

  • Normality is a unit of concentration that is defined as the number of equivalent weights of solute per liter of solution. 
  • It is commonly abbreviated as N and is expressed in equivalents per liter (eq/L).
