Each of the two platinum electrodes having area 64 `mm^(2)` of a conducitvity cell are separated by 8mm. The resistance of the cell containing `7.5xx10^(-3)` M KCI solution at 298 K is 1250 ohm calculate
(i) Cell constant
(ii) Conductivity and
(iii) Molar conductivity

Explanation

To solve the problem step by step, we will calculate the cell constant, conductivity, and molar conductivity of the KCl solution in the conductivity cell.

### Step 1: Calculate the Cell Constant

The cell constant (k) is calculated using the formula:
\[ k = \frac{L}{A} \]
where:
- \( L \) is the distance between the electrodes (in cm)
