λ m =(1000 k / C )=(1000 × 6.3 × 10-2/0.1) =630 ohm -1 cm 2 mol -1

Q. Specific conductance of $0.1 M H N O_{3}$ is $6.3 \times 1 0^{- 2} o h m^{- 1} c m^{- 1}$ . The molar conductance of the solution is

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

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

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

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

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