Molarity =

Number of moles of solute

Volume of solution (in L)

Molality =

Number of moles of solute

Mass of solvent (in kg)

Mole fraction =

Number of moles of component

Total number of moles of all components

Weight fraction of solute =

Weight of a component

Total weight of solution

$$ \times $$ 100

KEY Concept : Those units which are volume related will be affected by the change in temperature.

The definition of molarity is - Number of moles of solute present in one litre of solution. From definition you can see it is depends on volume which increases with increasing temperature and decreases with decreasing temperature.

All the other three options (Molality, Mole fraction, Weight fraction of solute) are mass related units and temperature has no effect on mass.
