हिन्दीThe molar conductivity of a \( 0.5 \mathrm{~mol/dm}^3 \) solution of \( \mathrm{AgNO}_3 \) with electrolytic conductivity of \( 5.76 \times 10^{-3} \mathrm{~S~cm}^{-1} \) at \( 298 \mathrm{~K} \) is ______.
Correct answer · Option 3
\( 11.52 \mathrm{~S~cm}^2/\mathrm{mol} \)
Explanation
\( \Lambda_m = \frac{\kappa \times 1000}{M} = \frac{5.76 \times 10^{-3} \times 1000}{0.5} = \frac{5.76}{0.5} = 11.52 \mathrm{~S~cm}^2/\mathrm{mol} \).
