Answer 1

Answer: (D)

. $630oh{m}^{-1}c{m}^{2}mol{e}^{-1}$

Given that,

Molar concentration of Nitric acid : 0.1M

Specific conductance of Nitric acid is $6.3\times {10}^{-2}oh{m}^{-1}c{m}^{-1}$

${\lambda }_m=\frac{k\times 1000}{M}$
${\lambda }_m=\frac{k\times 1000}{M}=\frac{6.3\times {10}^{-2}\times 1000}{0.1}=6.3\times {10}^2$

$=630oh{m}^{-1}c{m}^{2}mo{l}^{-1}$
