Question

The molar conductivity of \(0.5 \, \text{mol/dm}^3\) solution of \(AgNO_3\) with electrolytic conductivity of \(5.76 \times 10^{-3} \, \text{S cm}^{-1}\) at \(298\,K\) is:

• A. \(0.086 \, \text{S cm}^2\text{/mol}\)
• B. \(28.8 \, \text{S cm}^2\text{/mol}\)
• C. \(2.88 \, \text{S cm}^2\text{/mol}\)
• D. \(11.52 \, \text{S cm}^2\text{/mol}\)

Hint:

While calculating molar conductivity, always remember the formula: \[ \Lambda_m = \frac{\kappa \times 1000}{C} \] where concentration must be in \(\text{mol L}^{-1}\).
