At certain temperature and infinite dilution , the equivalent conductances of sodium benzoate , hydrochloric acid , and sodium chloride are 240, 349 and 229 Omega^(-1) cm^(2) eq^(-1) respectively . The equivalent conductance of benzoic acid in Omega^(-1) cm^(2) eq^(-1) at the same condition is

Answer»

80
328
360
408

Solution :`Lambda_(C_(6)H_(5) COOH)^(@) = Lambda_(C_(6)H_(5) COONa)^(@) + Lambda_(HCl)^(@) - Lambda_(NACL)^(@)`
`Lambda_(C_(6)H_(5) COOH)^(@) = 240 + 349 - 229`
`Lambda_(C_(6)H_(5) COOH)^(@)= 240 + 349 - 229`
`Lambda_(C_(6)H_(5)COOH)^(@) = 360 Omega^(-1) CM^(2) eq^(-1)`
