Physical Chemistry
The molar conductivity of a strong electrolyte at infinite dilution is 426 S·cm²/mol. If the degree of dissociation is 100%, the conductivity of 0.01 M solution is:
Correct Answer:
C. 0.426 S·cm²/mol
EXPLANATION
κ = Λₘ × C = 426 × 0.01 = 4.26 S/cm. This needs conversion: κ = 4.26 × 10⁻² S/cm = 0.426 S/cm. Molar conductivity doesn't change; conductivity does.
