  For a salt XY, which is a strong electrolyte, the plot of \(\Lambda_m\) versus \(\sqrt{c}\) has a slope of \(-90.0\text{ S cm}^2\text{ mol}^{-3/2}\text{ L}^{1/2}\) at \(298\text{ K}\). At \(0.01\text{ M}\) concentration of XY, the value of \(\Lambda_m\) is \(145.0\text{ S cm}^2\text{ mol}^{-1}\). The limiting molar conductivity of \(\text{Y}^-\) ion (\(\lambda^\circ_{\text{Y}^-}\), in \(\text{S cm}^2\text{ mol}^{-1}\)) at \(298\text{ K}\) will be (Given: \(\lambda^\circ_{\text{X}^+} = 74.0\text{ S cm}^2\text{ mol}^{-1}\))
