Explanation:The concentration of a solution can be given in moles of solute dissolved per kilogram of solvent.

This is known as molality.

(Not to be confused with molarity which is a different measure of concentration.)

molality = moles of solute ÷ mass of solvent in kilograms

m = n(solute) ÷ mass(solvent in kg)
