5. Round platinum electrodes with a diameter of 1.54 cm are placed in a vessel for measuring electrical conductivity at a distance of 1.82 cm from each other. The vessel is filled with a 0.05 N solution of potassium nitrate. At a field strength of 0.6 V, a current of 1.9 mA passes through the solution. Calculate the specific and molar electrical conductivity of the test solution.
