Question

Which one of the following concentration units is independent of temperature? *​

Answer 1

Answer:

Molality and mole fraction are independent of temperature as both are w/w relations.

Explanation:

Answer 2

Answer:

Molality and mole fraction

Explanation:

We know Molarity=1LofsolutionNo.ofmolesofsolute

Normality=1LofsolutionNo.ofgramequivalentweightofsolute

Both Molarity and Normality depends on volume of solution and as we know volume varies with temperature variation.

Whereas Molality=1kgofsolventNo.ofmolesofsolute

Molality is independent of temperature as mass is independent of temperature.

Also, Mole fraction=TotalmolesNoofmoles is independent of temperature.
