Resistance of a conductivity cell (cell constant 129 m ) filled with 74.5 ppm solution of KCl is 100 — Electrochemistry Chemistry Question

Question

Resistance of a conductivity cell (cell constant 129 m ) filled with 74.5 ppm solution of KCl is 100 Ω (labelled as solution 1). When the same cell is filled with KCl solution of 149 ppm, the resistance is 50 Ω (labelled as solution 2). The ratio of molar conductivity of solution 1 and solution 2 is i.e. = x × 10 . The value of x is _____. (Nearest integer) Given, molar mass of KCl is 74.5 g mol –1 –3 –1
