Calculate the degree of dissociation ($\alpha$) of acetic acid, if its molar conductivity ($\Lambda_m$) is $39\cdot05\text{ S cm}^2\text{ mol}^{-1}$ (Given $\lambda^\circ_{(\text{H}^+)} = 349\cdot6\text{ S cm}^2\text{ mol}^{-1}$ and $\lambda^\circ_{(\text{CH}_3\text{COO}^-)} = 40\cdot95\text{ S cm}^2\text{ mol}^{-1}$)
