For a salt XY, which is a strong electrolyte, the plot of $\Lambda_{m}$ versus $\sqrt{c}$ has a slope of $-90.0~S~cm^{2}mol^{-3/2}L^{1/2}$ at 298 K. At 0.01 M concentration of XY, the value of $\Lambda_{m}$ is $145.0~S~cm^{2}mol^{-1}$. The limiting molar conductivity of $Y^{-}$ ion $(\lambda_{Y^{-}}^{0}$, in $S~cm^{2}~mol^{-1}$) at 298 K will be (Given : $\lambda_{X^{+}}^{0}=74.0~S~cm^{2}mol^{-1})$
