The electrical resistance of a column of 0.05 M KOH solution of diameter 1 cm and length 45.5 cm is 4.55 × 10³ ohm. Calculate its molar conductivity.

Calculate the molar conductivity and degree of dissociation. Conductivity of 2.5 × 10⁻⁴M methanoic acid is 5.25 × 10⁻⁵ Scm⁻¹. Given : $\Lambda^{0}(\mathrm{H}^{+})=349.5\,\mathrm{S}\,\mathrm{cm}^{2}\,\mathrm{moI}^{-1}\,\mathrm{and}\,\Lambda^{0}(\mathrm{HCOO}^{-})$ = 50.5Scm² mol⁻¹

When a certain conductance cell was filled with 0.1 M KCl, it has a resistance of 85 ohm at 25°C. When the same cell was filled with an aqueous solution of 0.052 M unknown electrolyte, the resistance was 96 ohms. Calculate the molar conductance of the electrolyte at this concentration. [Specific conductance of 0.1 M KCl = 1.29 × 10⁻² ohm⁻¹ cm⁻¹]
