Question

The unit of molar conductivity is:

RankGuru · Accepted Answer

**Molar Conductivity** ($\Lambda_m$) is the conducting power of all the ions produced by dissolving one mole of an electrolyte in solution.
- Formula: $\Lambda_m = \frac{\kappa 	imes 1000}{M}$, where $\kappa$ is specific conductivity and $M$ is molarity.
- **Units**:
- $\kappa$ (Specific conductivity): $S \, cm^{-1}$ (where $S = 	ext{Siemens}$ or $ohm^{-1}$).
- Concentration: $mol \, L^{-1}$ (which converts to $mol \, cm^{-3}$).
- Resulting Unit: $\frac{S \, cm^{-1}}{mol \, cm^{-3}} = \mathbf{S \, cm^2 \, mol^{-1}}$.
