The variation of $\lambda_{m}$ of acetic acid with concentration is correctly represented as:

$0.01\, S\, m^2\, mol^{-1} = $ ....... $S\, cm^2\, mol^{-1}$

Equivalent conductivity at infinite dilution for sodium potassium oxalate $[(COO^{-})_{2} Na^{+} K^{+}]$ will be (given molar conductivities of oxalate, $K^{+}$ and $Na^{+}$ ions at infinite dilution are $148.2$, $50.1$, and $73.5 \ S \ cm^{2} \ mol^{-1}$ respectively).

The resistance of a $0.01\, M$ solution of an $Hg_2Cl_2$ electrolyte was found to be $210\, \Omega$ at $298\, K$ using a conductivity cell with a cell constant of $0.63\, m^{-1}$. The equivalent conductance of the solution is:

Cell constant of a conductivity cell is $0.9 \ cm^{-1}$ and resistance shown by $AgNO_3$ solution is $6530 \ \Omega$. What is the conductivity of $AgNO_3$ solution?
