molarity- In chemistry, molarity is a concentration unit, defined to be the number of moles of solute divided by the number of liters of solution.
molality- Molality, also called molal concentration, is a measure of the concentration of a solute in a solution in terms of amount of substance in a specified amount of mass of the solvent. This contrasts with thedefinition of molarity which is based on a specified volume of solution.

Hey friend!!!
MOLARITY: The number of gram molecules of solute dissolved in one litre of solution is said to be molarity of the solution.
It is denoted by 'M' and it's unit is mol per litre.
Molarity= number of moles of solute/ volume of solution in litre.
MOLALITY: The number of gram molecules of solute dissolved in one kg of solvent is said to be molality of the solution.
It is denoted by 'm'.
Molality= number of moles of solute / amount of solvent (in kg)
