Resistance of a conductivity cell (cell constant 129 m -1 ) filled with 74.5 ppm solution of KC1 is 100 
(labelled as solution 1). When the same cell is filled with KC1 solution of 149 ppm, the resistance is 50 
(labelled as solution 2). The ratio of molar conductivity of solution 1 and solution 2 is i.e. 
. The value of x is_____.(Nearest integer)Given, molar mass of KC1 is 74.5 g mol -1
Text Solution
Verified by ExpertsThe correct answer is:
1000
(1000)
KCl solution 1 :
74.5 ppm, R 1 = 100 
KCl solution 2 :
149 ppm, R 2 = 50 
149 ppm, R 2 = 50
