The equivalent conductance of a solution if the concentration is $\frac{\mathrm{N}}{10}$, observed r

Question

The equivalent conductance of a solution if the concentration is $\frac{\mathrm{N}}{10}$, observed residence is $2.5 	imes 10^{3}$ ohms and cell constant is $1.25 \mathrm{~cm}^{-1}$.\

$\mathrm{K}=\mathrm{GG}^{*}=\frac{1}{\mathrm{R}} 	imes \mathrm{G}^{*}=\frac{1}{2.5 	imes 10^{3} \mathrm{ohm}} 	imes 1.25 \mathrm{~cm}^{-1}$\ $=5 	imes 10^{-4} \mathrm{ohm}^{-1} \mathrm{~cm}^{-1}$\ $\lambda \mathrm{equ}=\frac{\mathrm{K} 	imes 1000}{\mathrm{~N}}=\frac{5 	imes 10^{-4} 	imes 1000}{0.1}=5 \mathrm{ohm}^{-1} \mathrm{~cm}^{2} \mathrm{equ}^{-1}$\
