Answer 2

Molality is a method of expressing the concentration of a solution.

Explanation:

Molality: It is defined as the numbers moles of solute present in 1Kg of solvent.

According to the question,

• Number of mole = n
• Mass of solute= 1 kg

So, according to the definition the formula →$m =\frac{no. mole}{mass of solvent}$

Putting the value, $m= \frac{n}{1} \\m= n$
