Electrochemistry

The molar conductivity of a conductivity cell filled with 10 moles of 20 mL NaCl solution is \({\Lambda _{m1}}\) and that of 20 moles another identical cell heaving 80 mL NaCl solution is \({\Lambda _{m2}}\). The conductivities exhibited by these two cells are same. The relationship between \({\Lambda _{m2}}\) and \({\Lambda _{m1}}\) is
