For a salt XY, which is a strong electrolyte, the plot of $\Lambda_m$ versus $\sqrt{c}$ has a slope of –90.0 S cm² mol⁻³/² L¹/² at 298 K. At 0.01 M concentration of XY, the value of $\Lambda_m$ is 145.0 S cm² mol⁻¹. The limiting molar conductivity of Y⁻ ion ($\lambda_{Y⁻}^°$, in S cm² mol⁻¹) at 298 K will be

(Given : $\lambda_{X^+}^°$ = 74.0 S cm² mol⁻¹)
