Question

The specific conductance of a salt of 0.01 M
concentration is 1.061 x 10-4 S cm-1. Molar
conductance of the same solution will be :
(1) 1.061 x 10-4 S cm mol-1
(2) 1.061 S cm mol-1
(3) 10.61 S cm mol-1
(4) 106.1 S cm mol-1​

Answer 1

The specific conductance κ, the molar conductance Λm and molar concentration Care related by the expression,

Λm=C1000 κ

Λm=0.01 mol/L1000 cm3/L×1.061×10−4 S/cm

Λm=10.61 S cm2 /mol
