A) temperature
B) concentration
C) pressure
D) all of these
Correct Answer: A
Solution :
Molality is the number of moles of solute present in 1000 g or 1 kg of solvent mathematically \[m=\frac{mass\,of\,solute\,(g)\times 100}{molecular\,mass\,of\,solute\,\times mass\,of\,solvent\,(g)}\] It is clear that molality will not change with temperature as it does not involve volume of the solution.
