Question

among the molarity and molality which one is the best to express concentration​

Answer 1

Answer:-

Molality Is Better Than Morality

Explanation

As we know that

$Molarity = \frac{Number \: of \: mole}{Volume \: of \: solution}$

and

$Molality = \frac{Number \: of \: mole}{Weight \: of \: solvent}$

so we observe that in the molarity ,volume factor came the also according to the Charles Law

$V \: \: \alpha \: \: T$

means that the molarity can change on changing the temperature but in molality there is no such factor which changes with the change in external environment

Conclusion:-

Molality is better than molarity because molarity varies with temperature means we get different value of molarity at different temperatures.....
