DEFINITION


    The molarity (M) of a solution is the number of moles of solute 
    dissolved in one liter of solution. To calculate the molarity of a solution, 
    divide the moles of solute by the volume of the solution expressed in liters.



    Molality is defined as the “total moles of a solute contained in a kilogram of a solvent.
    Molality is also known as molal concentration. It is a measure of solute concentration 
    in a solution. The solution is composed of two components; solute and solvent.
