The correct answer is Option (2) → $ohm^{-1}$
- Conductance (G) is the reciprocal of resistance (R). G = 1/R
- Unit of resistance is ohm (Ω), so unit of conductance is ohm⁻¹ or siemens (S). 1 S = 1 ohm⁻¹
Other options:
- S/m: This is the unit of conductivity (κ), not conductance.
- S cm² mol⁻¹: This is the unit of molar conductivity (Λₘ).
- ohm cm² mol⁻¹: This is an older unit sometimes used for molar resistivity, not conductance.
