Specific conductance of a solution is the conductance of a portion

  • A.containing 1 mole of solute
  • B.of unit mass at unit temperature
  • C.1 cm\( ^3 \) in volume between electrodes 1 cm apart
  • D.containing 1 gram equivalent of solute

Answer: C

It is the reciprocal of resistivity, has units of siemens per centimetre, and rises with concentration because more ions are present in the fixed volume. The equivalent and molar conductances refer instead to a fixed amount of solute.
