Question

The equivalent conductivity of a solution containing 2.54g of CuSO4 per liter is 91.0 \( \Omega^{-1} \, \text{cm}^2 \). The conductivity would be?

• A. \( 29.10^{-3} \, \Omega^{-1} \, \text{cm}^{-1} \)
• B. \( 18.10^{-3} \, \Omega^{-1} \, \text{cm}^{-1} \)
• C. \( 24.10^{-4} \, \Omega^{-1} \, \text{cm}^{-1} \)
• D. \( 36.10^{-8} \, \Omega^{-1} \, \text{cm}^{-1} \)

Hint:

The conductivity of a solution is proportional to the concentration and the equivalent conductivity.

Answer 1

The Correct Option is A

The conductivity is calculated using the formula: \[ \kappa = \lambda \cdot c \] where \( \lambda \) is the molar conductivity and \( c \) is the concentration.
