The molar conductivities at infinite dilution $\Lambda_{\mathrm{m}}^{0}$ for $\mathrm{Na}_{2} \mathrm{SO}_{4}, \mathrm{K}_{2} \mathrm{SO}_{4}, \mathrm{KCl}, \mathrm{HCl}$ and HCOONa at 300 K are 260, 308, 150, 426 and $105\,\mathrm{S\,cm^{-1}\,mol^{-2}}$ respectively. Hence $\Lambda_{\mathrm{m}}^{0}$ for formic acid in the same unit and at the same temperature is
