Question

The resistivity of a 0.2M solution of electrolyte is
5x10^- 3 ohm cm, calculate it molar conductivity​

Answer 1

Explanation:

The resistivity of a 0.2M solution of electrolyte is

5x10^- 3 ohm cm, calculate it molar conductivity

Answer 2

Answer:

Here the resistivity = 5×10^-3 ᘯcm

Therefore,

The conductivity of solution

k=1/p

=1/5×10^-3 ᘯcm

=1/5×10^3 ᘯ^-1 cm^-1

Molar conductivity

^M=1000×k/M

=10^3×1/5×10^3×1/0.8

=2.5×10^5 ᘯ^-1 cm^2 mol^-1.
