Solution

The correct option is D
2.9 x 10^-3W^-1cm^-1

$N o r m a l i t y o f C u S O_{4}$
$N = \frac{w}{E} \times \frac{1000}{V_{m l}} = \frac{2.54}{\frac{159.5}{2}} \times \frac{1000}{1000} = 0.032 N$
$\land_{e q} = \frac{κ \times 1000}{N}; 91 = \frac{κ \times 1000}{0.032;}; κ = 2.9 \times 10^{- 3} Ω^{- 1} . c m^{- 1}$
