κ=2.14.2×150=0.01ohm−1cm−1
Equivalent conductance is the conductivity of a solution containing 1 g-equivalent of the electrolyte.
Λeq=κ V
V is volume of solution containing 1 g−equiv
Normality of solution→N
N g−equiv of solute present in →1 L solution
1 g−equiv of solute present in →1N L solution
∴
Λeq=κN (when volume in litres)
Λeq=κ×1000N (when volume in cm3)
Λeq=0.01×10001
Λeq=10ohm−1cm2eq−1
