The standard international (SI) unit for molar conductivity, \( \Lambda_m \), is expressed as: \[ S \, m^2 \, \text{mol}^{-1} \] In this expression:
- \( S \) (Siemens) denotes the unit of electrical conductivity,
- \( m^2 \) indicates the area over which the conductivity is measured,
- \( \text{mol}^{-1} \) signifies per mole of the solution's electrolyte.
