The molar conductivity of a 0.02 M KCL solution is 149.2 S cm2 mol-1. Calculate the value of the cell constant if the electrical resistance of the solution is 480 ohm.
Dear Student,
Given, Resistance = 480 Ohm
Conductivity= 149.2 S cm2 mol-1
Formula used for calculating cell constant
Conductivity (k) = Cell Constant /Resistance (R)
Cell Constant = k x R
Given, Resistance = 480 Ohm
Conductivity= 149.2 S cm2 mol-1
Formula used for calculating cell constant
Conductivity (k) = Cell Constant /Resistance (R)
Cell Constant = k x R
= κ × R =149.2 * 480 =71616 cm-1
