The Molar conductance of the solution is 10³.

Quantity of solution = 0.01M (Given)

Resistance = 40 ohms (Given)

Cell constant = 0.4 cm⁻¹, (Given)

Thus,

The molar conductance will be calculated as -

= 1/ Resistance × Cell constant / Mol concentration

= 1/40 × 0.4 / 0.01 × 10`³

= 10³

Therefore, the concentration of the mole is 10³cm²mol.
