(A) The formula for equivalent conductivity is $\lambda_{eq} = \frac{1000 \times \kappa}{N}$,where $\kappa$ is the specific conductance and $N$ is the normality of the solution.For $H_2SO_4$,the molarity is $1 \, M$,so the normality $N = M \times \text{n-factor} = 1 \times 2 = 2 \, N$.Substituting the values: $\lambda_{eq} = \frac{1000 \times 26 \times 10^{-2}}{2} = \frac{260}{2} = 130 \, S \, cm^2 \, eq^{-1} = 1.3 \times 10^2 \, S \, cm^2 \, eq^{-1}$.
