Difference between molarity and molality.
Molality=no. of moles of solute present in 1kg of solvent………….Molarity =no.of moles of solute present in 1 lt.of solution…………..
No of moles per liter of solution called molarity while no of moles per kg of solvent called molarity
Molarity : The no of moles of solute present in 1 liter of solution. : SI unit is mol / liter.Molality : The no of moles of solute present in 1kg of solvent. : SI unit is mol / kg.
moles per litre is called molarity moles per kg called molality
Molarity is the no. Of moles of solute per litre of soln. Molality is no. Of moles of solute per kg of solvent
