  "id": "MLC-T-CHM-011431",
  "term": "Stoichiometric mean molal",
  "field": "Chemistry",
  "definition": "A measure of the average molality of ions in an electrolyte solution, taking into account the stoichiometric coefficients of the dissociation reaction. It is calculated as the geometric mean of the molalities of the individual ions, raised to the power of their respective stoichiometric coefficients. This quantity is used in expressions for activity coefficients of electrolytes.",
