Question

Which of the following changes with temperature?
(A) Molality
(B) Molarity
(C) % w/w
(D) Mole fraction

Answer 1

(D) mole fraction is the answer. Hope it help

Answer 2

Molarity changes with temperature.

Explanation:

Molarity is defined to be the number of moles of solute divided by the number of liters of solution. Molarity is an unit of concentration.

Molarity is denoted by C.

Its formula,

                   $C = \frac{n}{V}$.

  where:    

      C = Molarity.

       n = Moles of solute.

       v =moles of solution.

Volume depends upon temperature. With the increase in  temperature, the volume can either increase or decrease.

In the formula of molarity, the volume is on the denominator. Therefore with the change in temperature the molarity of solution changes.
