Why is molarity independent of temperature? [closed]
WebMay 28, 2024 · One of the key attractions of molality is that changing the temperature of a solution does not change the molality, while it may change the molarity. ... The downside, of course, is that the amount of solute required to reach a given molality depends on the nature of the solvent; ambiguity may also arise when a mixed solvent system (e.g. a ... WebActivity depends on temperature, pressure and composition of the mixture, among other things. ... these values would all be unity.
