Resistance of a0.1M KClsolution in a conductance cell is300 ohmand specific conductance of0.1M KClis1.33 ×10-2ohm-1cm-1. The resistance of0.1M NaClsolution in the same cell is400ohm. The equivalent conductance of the0.1M NaClsolution (inohm-1cm2/gmeq.) is

Answer:
100.00
Solution:

κ=1RlA
i.e.lA=R×κ=300×1.33×10-24.0cm-1
κNaCl=1RlA=1400×4.0
Λm(NaCl)=κ×1000M=4.0400×10000.1=100
