how does resistance relate to conductivity? R = 1/G & resistivity = 1/conductanc
« on: October 29, 2009, 02:13:08 AM »
The molar conductivity 0.1 M KCl(aq) at 250C is 129 S cm2 mol-1. The measured
resistance in a conductivity cell was 28.44 W. The resistance was 28.50 W when the
cell contained 0.1 M NH4Cl. Calculate the molar conductivity of NH4Cl(aq) at this
concentration.

Please suggest how do i go about solving this problem?

Use KCl data to calculate cell constant.
