  Differentiate between molality and molarity of solution. What is the effect of change in temperature of a solution on its molality and molarity?                                                                                                                                       2

Answer:

   

Molality	Molarity
1. No. of moles of solute present in 1 kg or 1000 gm of    solvent.  2.	No. of moles of solute dissolved in per litre of solvent.                                                                   1

  Effect of temperature: (a) Molality is not affected by increase in temperature.                                                                                                   (b) Molarity increases with increase 'in temperature.
