At a certain temperature and at infinite dilution, the equivalent conductances of sodium benzoate, hydrochloric acid and sodium chloride are 240, 349 and 229 ohm−1^{-1} cm2^2 equiv−1^{-1} respectively. The equivalent conductance of benzoic acid in ohm−1^{-1} cm2^2 equiv−1^{-1} at the same conditions is:
