kappa=6.3 × 10-2 ohm -1 cm -1, C=0.1 M Lambdam= kappa × (1000/C)=6.3 × 10-2 × (1000/0.1)=630 ohm -1 cm 2 mol -1

Q. Specific conductance of $0.1 M$ nitric acid is $6.3 \times 1 0^{- 2} o h m^{- 1} c m^{- 1} .$ The molar conductance of the solution is

$630 o h m^{- 1} c m^{2} m o l^{- 1}$

$315 o h m^{- 1} c m^{2} m o l^{- 1}$

$6.300 o h m^{- 1} c m^{2} m o l^{- 1}$

$63.0 o h m^{- 1} c m^{2} m o l^{- 1}$

$κ = 6.3 \times 1 0^{- 2} o h m^{- 1} c m^{- 1}, C = 0.1 M$

$Λ_{m} = κ \times \frac{1000}{C} = 6.3 \times 1 0^{- 2} \times \frac{1000}{0.1} = 630 o h m^{- 1} c m^{2} m o l^{- 1}$
