Answer 2

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

Explanation :

Molar conductance : It is defined as 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.

The molar conductance is represented by ($\Lambda _m$).

Given:

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

Molarity of the KCl solution,M = 0.20 M

Formula used :

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

Now put all the given values in this formula, we get:

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

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