Question

Resistance of a conductivity cell filled with a solution of an electrolyte of concentration $0.1M$ is $100\Omega$. The conductivity of this solution is $1.29S{m}^{-1}$. Resistance of the same cell when filled with $0.2M$ of the same solution is $520\Omega$. The molar conductivity of $0.02M$ solution of electrolyte will be :

• A. $1.24\times {10}^{-4}S{m}^{2}mo{l}^{-1}$
• B. $12.4\times {10}^{-4}S{m}^{2}mo{l}^{-1}$
• C. $124\times {10}^{-4}S{m}^{2}mo{l}^{-1}$
• D. $1240\times {10}^{-4}S{m}^{2}mo{l}^{-1}$

Answer 1

The correct option is C $124\times {10}^{-4}S{m}^{2}mo{l}^{-1}$
