Molar Conductivity (${\Lambda }_m$) is the conducting power of all the ions produced by dissolving one mole of an electrolyte in solution.

• Formula: ${\Lambda }_m=\frac{\kappa \times 1000}{M}$, where $\kappa$ is specific conductivity and $M$ is molarity.
• Units:
• $\kappa$ (Specific conductivity): $Sc{m}^{-1}$ (where $S=\text{Siemens}$ or $oh{m}^{-1}$).
• Concentration: $mol{L}^{-1}$ (which converts to $molc{m}^{-3}$).
• Resulting Unit: $\frac{Sc{m}^{-1}}{molc{m}^{-3}}=\mathbf{S}\mathbf{c}{\mathbf{m}}^2\mathbf{mo}{\mathbf{l}}^{-1}$.
