The molar conductivity of a 0.5 mol / dm3 solution of AgNO3 with electrolytic conductivity of 5.76 × 10-3 S cm-1 at 298 K is
28.8 S cm2 /mol
2.88 S cm2 /mol
11.52 S cm2 /mol
0.086 S cm2 /mol
Explanation:
$\lambda^{o}_{M} = \dfrac{k \times 1000}{M} = \dfrac{5.76 \times 10^{-3} \times 1000}{0.5}$
= 11.52 S cm2 mol-1
