Question

If the conductivity of 0.08 M KCl solution is 2 × 10^-2 Ω^-1, what is the molar conductivity of the solution?

Options

• 350 Ω^-1 cm² mol^-1

• 25.0 Ω^-1 cm² mol^-1

• 250 Ω^-1 cm² mol^-1

• 0.25 Ω^-1 cm² mol^-1

Answer 1

250 Ω^-1 cm² mol^-1

Explanation:

Λ = `(1000  "k")/"C" = (1000 xx 2 xx 10^-2)/0.08`

= 250 Ω^-1 cm² mol^-1
