The variation of molar conductivity of strong electrolytes with dilution

Can be calculated from the following equation: 204-526_img43-300x20.gif
This equation is called Debye Huckel Onsager equation.

are the molar conductances at a given concentration and at infinite dilution (respectively). b is a constant depending on the viscosity of the solvent.

√C is the square root of the concentration.
here
^m=to calculate
^m0=348.5
C=.05M
K=empirical constant of the solvent,here water=5.4muS/m

calculate and find the answer
