The cell constant tells us about the cell's design and size. It can be found by using the known conductivity and resistance of 0.1 M KCl solution. G⋆=κ⋅R So, G⋆=1.29×100=129m−1 or 1.29cm−1 Step 2: Calculate the conductivity ( κ ) for 0.02MKCl solution We use the cell constant and the new measured resistance for the 0.02 M solution. κ=‌
