For a salt XY\mathbf{XY}, which is a strong electrolyte, the plot of Λm\Lambda_m versus c\sqrt{c} has a slope of −90.0 S cm2 mol−3/2 L1/2-90.0\ \mathrm{S\,cm^2\,mol^{-3/2}\,L^{1/2}} at 298298 K. At 0.010.01 M concentration of XY\mathbf{XY}, the value of Λm\Lambda_m is 145.0 S cm2 mol−1145.0\ \mathrm{S\,cm^2\,mol^{-1}}. The limiting molar conductivity of Y−\mathbf{Y^-} ion (λY−0\lambda^0_{Y^-}, in S cm2 mol−1\mathrm{S\,cm^2\,mol^{-1}}) at 298298 K will be (Given : λX+0=74.0 S cm2 mol−1\lambda^0_{X^+} = 74.0\ \mathrm{S\,cm^2\,mol^{-1}})
