(A) The degree of ionization $(\alpha)$ is given by the ratio of molar conductance at a specific concentration $(\lambda^c_m)$ to the molar conductance at infinite dilution $(\lambda^\infty_m)$: $\alpha = \frac{\lambda^c_m}{\lambda^\infty_m} = \frac{9.54}{238} \approx 0.04008$ To express this as a percentage: $\% \alpha = \alpha \times 100 = 0.04008 \times 100 = 4.008 \%$
