Answer 2

Answer:

The molar conductance of the KCl in its solution is $124 S/cm^2 mol$.

Explanation:

Molar conductance ($\Lambda _m$) is the conductance of all the ions produced by 1 mole of electrolyte on dilution when the electrodes are 1 cm apart and the area of the electrodes is large enough to hold the whole solution.

Molar conductivity of solution = $\Lambda _m$

Specific conductance  of KCl = $\kappa =0.0248 S/cm$ (missing)

Molarity of the KCl solution,M = 0.20 M

$\Lambda _m=\frac{\kappa \times 1000}{M}$

$=\frac{0.0248 S/cm\times 1000}{0.20 M}=124 S/cm^2 mol$

The molar conductance of the KCl in its solution is $124 S/cm^2 mol$.
