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 = `"Number of moles of solute"/"Solvent in kg"`
So, temperature has no effect on the morality of the solution because morality is expressed in mass.
