Question
Volume of a solution changes with change in temperature, then, will the molality of the solution be affected by temperature? Give reason for your answer.
Solution
Molality is the number of moles of substance (also known as the solute) found in a given mass of solvent (in Kg) in which it is dissolved. Molality is calculated by using the formula.
Molality =
So, temperature has no effect on the morality of the solution because morality is expressed in mass.
