Question

Which one of the following concentration unit does not depend
on temperature ?
A Normality
B. Molarity
C. Molality
D. All of these​

Answer 1

answer is molality

because normality and molarity depends on volume

volume is directly proportional to temperature

(PV=nRT )

whearas molality is independent of volume

Answer 2

To find Concentration of solution

Explanation:

Concentration of solution

It refers to the amount of solute that is present in given solution.

There are certain physical quantities by which we can measure concentration of solution .

Out of them Normality ,Molarity ,Molality are there.

Let us define them :

Normality : It is the amount of number of gram equivalents present per litre of solution .

Molarity : It is the number of moles present per litre of solution .

Molality : It is the number of moles of solute present in 1 kg of solvent

Out of them , the quantities that depends on volume vary with temperature that is normality and molarity but not molality .

Therefore the correct answer is "Molality ".
