Answer:

Molality is the measurement of how much concentration is present in a solution by dividing the moles of solute by the kilograms of the solution that the solute was dissolved in.

Explanation:

Molality is the measurement of the solute or the molal concentration of the substance in the mass of the solvent. It is best described as, the number of moles of solute in a kilogram of solvent.

What is the difference between molality and molarity?

Molality and molarity are the property of the solution that defines the concentration of the solute dissolved in the solvent to form a solution. Molality gives the solute concentration as the ratio of the moles of the solute dissolved in the 1 kilogram or 1000 gm of solvent.

Molarity gives the concentration of the solute as the ratio of the moles of the solute dissolved in 1L or 1000 mL of the solvent. Hence, molarity is based on volume and molality on the mass of the solvent.

Therefore, molality is the solute concentration in a mass of the solvent.
