Given:
The resistance of a 0.5 M solution of an electrolyte enclosed between two Platinum electrodes 1.5 cm apart and having an area of cross-section 2.0 cm² was found to be 30 ohms.
To Find:
Calculate the molar conductivity of the solution.
Solution:
We all know that,
Specific conductance={(resistance) * (cross-sectional area)}
or, к
or, к=
Therefore, к=Ω
Now, Molar conductance = (1000*к)*
or, ∧ₙ
or, ∧ₙ Ωm²
Therefore, the molar conductivity of the solution is 50Ωm².
