Question

For an electrolyte solution of $0.05$ $M$, the conductivity has been found to be 0.0110 S $c{m}^{-1}$. The molar conductivity is:

• A. $0.055$ $Sc{m}^{2}mo{l}^{-1}$
• B. $550$ $Sc{m}^{2}mo{l}^{-1}$
• C. $0.22$ $Sc{m}^{2}mo{l}^{-1}$
• D. $220$ $Sc{m}^{2}mo{l}^{-1}$

Answer 1

Answer: (D)

$220$ $Sc{m}^{2}mo{l}^{-1}$

${\Lambda }_m=\frac{k\times 1000}{M}=\frac{0.0110\times 1000}{0.05}$

$=220Sc{m}^{2}mo{l}^1$

Hence, option D is correct.
