Question

7. Which of the following concentration terms does not change with change in
temperaturo?
Normality
Molarity
Wole fraction
oo e a​

Answer 1

Answer:

Molarity is given by M=Vsolutionnsolute here V is the volume of the solution which is temperature dependent.

Molality is given by m=Wsolventnsolute Wsolvent is the mass of solvent which is independent of temperature.

Normality is given by N=Vsolutionnequivalent solute

Here, it is dependent on volume which is temperature dependent.

Mole fraction is  dependent on the amount of substance which is temperature independent.

Therefore, Molality and mole fraction are temperature independent.
