Question

When a certain conductance cell as filled with 0.1 M KCl, it has a resistance of 85 ohm at 25°C.

Answer 1

Calculation of cell constant  Conductivity of 0.1 M KCl = 1.29 x 10-2 Ω-1 cm-1   Resistance = 85 ohm Conductivity, Conductivity of unknown electrolyte K, Read more on Sarthaks.com - https://www.sarthaks.com/197061/when-a-certain-conductance-cell-as-filled-with-0-1-m-kcl-it-has-a-resistance-of-85-ohm-at-25cWhen a certain conductance cell as filled with 0.1 M KCl, it has a resistance of 85 ohm at 25°C. When the same cell was filled with an aqueous solution of 0.052 M unknown electrolyte, the resistance was 96 ohms. Calculate the molar conductance of the electrolyte at this concentration.
