Question

Specific conductance of 0.1m nitric acid is 6.3 ×10 tih the powe minus 2 ohm cm .The molar conductance

Answer 1

Answer:

The conductance is the property of the conductor (metallic as well as electrolytic) which facilitates the flow of electricity through it. It is equal to the reciprocal of resistance i.e.,

Conductance = \frac{1}{Resistance} = \frac{1}{R}

Units of conductance :  \Omega ^-^1

Answer 2

The molar conductance is $630ohm^{-1}cm^2mol^{-1}$

Explanation:

Specific conductance is the conductance for unit volume of a solution

$\kappa=C\times \frac{l}{a}$

where,

$\kappa$ =Specific conductance

C = Conductance

$\frac{l}{a}$ = cell constant

Molar conductance is defined as the conductance of all the ions produced by ionization of 1 g mole of an electrolyte when present in V mL of solution.

$\mu=\frac{\kappa\times 1000}{C}$

$\mu$= molar conductance  

$\kappa$ =Specific conductance  = $6.3\times 10^{-2}ohm^{-1}cm^{-1}$

c = concentration of the solution in mole per litre = 0.1 M

$\mu=\frac{6.3\times 10^{-2}ohmcm\times 1000cm^3}{0.1M}=630ohm^{-1}cm^2mol^{-1}$
