For same conductivity cell, \(G ^{*}\) is constant and hence \(\kappa . R .=\) constant.
\(\therefore 0.14 \times 4.19=\kappa \times 1.03\)
or,\(\kappa\) of HCl solution \(=\frac{0.14 \times 4.19}{1.03}\)
\(=0.5695\, Sm ^{-1}\)
\(=56.95 \times 10^{-2} Sm ^{-1} \approx 57 \times 10^{-2} \,Sm ^{-1}\)
