Question

The unit of molar conductance of an electrolyte solution will be

• A. $oh{m}^{-1}cmmo{l}^{-1}$
• B. $mhoc{m}^{2}mo{l}^{-1}$
• C. $ohmc{m}^{2}mo{l}^{-1}$
• D. $oh{m}^{-1}c{m}^{-1}mo{l}^{-1}$

Answer 1

Answer: (B)

${\Lambda }_m=\kappa \times \frac{1000}{C};C=$ molarity of solution

${\Lambda }_m=\frac{oh{m}^{-1}c{m}^{-1}}{molec{m}^{-3}}=oh{m}^{-1}mo{l}^{-1}c{m}^2$ or $mhomo{l}^{-1}c{m}^2$
