Molality is defined as the number of moles of solute per kilogram of solvent in a solution. Option D represents this definition accurately. Option A is incorrect as it uses ‘mole of solvent’ instead of ‘kilogram of solvent’. Option B is the definition of Avogadro's number, not molality. Option C is the definition of molarity, which is the number of moles of solute per liter of solution.
