Molality definitions
1/10
  • Molality
    A concentration measure defined as moles of solute per kilogram of solvent, unaffected by temperature changes.
  • Osmolality
    Also known as ionic molality, it accounts for the number of dissolved particles in a solution.
  • Solute
    The substance dissolved in a solvent to form a solution.
  • Solvent
    The substance in which a solute is dissolved to form a solution.
  • Covalent Compounds
    Compounds where atoms are bonded by shared electrons, typically not dissociating into ions.
  • Ionic Compounds
    Compounds that dissociate into ions when dissolved, affecting osmolality.
  • Sodium Chloride
    An ionic compound that dissociates into sodium and chloride ions in solution.
  • Temperature Independence
    A characteristic of molality, as it does not involve volume, remaining constant with temperature changes.
  • Moles
    A unit representing the amount of substance, used in calculating molality.
  • Kilograms
    The unit of mass for the solvent in the calculation of molality.
