The resistances of a series of aqueous solutions of NaCl prepared by carefully diluting a sample were measured with a cell with a cell constant of 0.2063 and the following values were found.

C/ (mol L-1 ) 0.00050 0.0010 0.0050 0.010 0.020 0.050

R/ohm 3314 1669 342.1 174.1 89.08 37.14

Show that the molar conductivity obeys Kohlrausch's law and find the boundary molar conductivity. Find the coefficient .

Find out

a) molar conductivity at infinite diluted,

b) the molar conductivity,

c) 0.010 mol L-1 NaI(aq) the cell of resistance at 25 C using these values of k, lambda (Na+ ) =5.01 mS m2 mol-1 and lambda (I- )=7.68 mS m2 mol-1 .

Please , solve the a, b and c options.
