Molar conductivity is a measure of a solution's ability to conduct electricity. It is calculated by dividing the conductivity of a solution by its molar concentration. The SI unit for molar conductivity is Siemens meters squared per mole.
Limiting molar conductivity is the molar conductivity of an electrolyte solution when its concentration approaches zero, or is at infinite dilution. It is represented by the symbol Λ°m.
