Question

Define molarity and molality .How does a change in temp influence their values

Answer 1

MOLARITY refers to the no. of moles of solute present in 1 L of solution.It is denoted by 'M'.

MOLALITY refers to the no. of moles of solute present in 1 kg of solvent.It is denoted by 'm'.

Effect of temperature :

temperature has no effect on MOLALITY but it affects MOLARITY since it involves the volume of solution,which in turn gets affected in a change in temperature.
