A cell whose resistance, when filled with \( 0.1 \mathrm{M} \) \( -\mathrm{KCl} \) is \( 200 \Omega \), is measured to be \( 6400 \Omega \), when filled with \( 0.003 \mathrm{M}-\mathrm{NaCl} \) solution. What is the molar conductance of \( \mathrm{NaCl} \) solution, in \( \Omega^{-1} \mathrm{~cm}^{2} \) \( \mathrm{mol}^{-1} \) if the molar conductance of \( 0.1 \mathrm{M}-\mathrm{KCl} \) is \( 120 \Omega^{-1} \mathrm{~cm}^{2} \mathrm{~mol}^{-1} \) ?
(a) \( 41.67 \)
(b) 250
