(A) The formula for molar conductivity is $\wedge_{m} = \frac{1000 \times \kappa}{c}$.Given conductivity $\kappa = 6.065 \times 10^{-4} \ \Omega^{-1} \ cm^{-1}$ and concentration $c = 0.005 \ M$.Substituting the values:$\wedge_{m} = \frac{1000 \times 6.065 \times 10^{-4}}{0.005} = \frac{0.6065}{0.005} = 121.3 \ \Omega^{-1} \ cm^2 \ mol^{-1}$.
