Which of the following solutions has the maximum conductivity?

Calculate the molar conductivity of $CH_2ClCOOH$ at zero concentration if molar conductivities of $HCl$,$KCl$,and $CH_2ClCOOK$ at zero concentration are $4.2$,$1.4$,and $1.1 \ \Omega^{-1} \ cm^2 \ mol^{-1}$ respectively.

What is the resistance of $0.01 \ M \ KCl$ solution if its conductivity is $200 \ \Omega^{-1} \ cm^{-1}$ and cell constant is $1 \ cm^{-1}$?

The resistance of a $0.2 \ M$ solution of an electrolyte is $30 \ \Omega$ and conductivity is $1.2 \ S \ m^{-1}$. What is the value of the cell constant (in $cm^{-1}$)?

Resistance of a conductivity cell at $298 \ K$ for $0.0100 \ M \ KCl$ is $161.8 \ \Omega$. Resistance becomes $190 \ \Omega$ when $0.005 \ M \ NaOH$ solution is filled in this cell. Calculate: $(i)$ cell constant,$(ii)$ specific conductivity for $NaOH$ solution,and $(iii)$ molar conductivity.

The conductivity $(\kappa)$ of a $0.02 \text{ M}$ $KCl$ solution at $298 \text{ K}$ is $0.0123 \text{ ohm}^{-1} \text{ cm}^{-1}$. If the resistance $(R)$ of the cell containing this solution is $120 \text{ ohm}$, what is the value of the cell constant $(G^*)$?
