Molality is the number of moles of solute per kilogram of solvent.

• Molality is a concentration unit used in chemistry.

• It is defined as the number of moles of solute per kilogram of solvent.

• It is different from molarity, which is the number of moles of solute per liter of solution.

• Molality is temperature-dependent, while molarity is not.

• For example, a solution containing 0.5 moles of NaCl in 1 kg of water has a molality of 0.5 mol/kg.
