Equal volumes of \( 0.015 \mathrm{M} \mathrm{CH}_{3} \mathrm{COOH} \& 0.015 \mathrm{M} \mathrm{NaOH} \) are mixed together. What would be molar conductivity of mixture if conductivity of \( \mathrm{CH}_{3} \mathrm{COONa} \) is \( 6.3 \times 10^{-4} \mathrm{~S} \mathrm{~cm}^{-1} \)
\( P \)
(A) \( 8.4 \mathrm{~S} \mathrm{~cm}^{2} \mathrm{~mol}^{-1} \)
(B) \( 84 \mathrm{~S} \mathrm{~cm}^{2} \mathrm{~mol}^{-1} \)
W.
(C) \( 4.2 \mathrm{~S} \mathrm{~cm}^{2} \mathrm{~mol}^{-1} \)
(D) \( 42 \mathrm{~S} \mathrm{~cm}^{2} \mathrm{~mol}^{-1} \)
