Question

Is molality affected by changes in temperature?

Answer 1

Explanation:

Molality is the number of moles of solvent per kilogram of solvent.

1. In the case of molality, moles are proportional to mass.
2. Mass remains constant at all temperatures, but molality does not change with temperature.
3. As the temperature increases, the solvent (${\mathrm{H}}_2\mathrm{O}$) evaporates or dissolves, As a result, the number of solutions and solvents varies, As a result, the temperature change affects each volume-dependent concentration element.
4. Since the molality of a solution is defined in terms of its mass rather than its volume, the temperatures do not affect it.
5. Molarity changes with temperature, It is defined as the number of moles of solute per liter of solution.
6. Because water expands as the temperature rises, the volume of the solution also increases, More liters have the same number of moles, but at higher temperatures and the molarity is lower.

Hence, molality is not affected by changes in temperature.
