075. Solving a chemistry problem

2. Platinum electrodes in the form of disks with a diameter of 1.3 cm are placed in a vessel for measuring electrical conductivity. The distance between the electrodes is 1.7 cm. The vessel is filled with 0.05 mol/l NaNO3. At a voltage of 0.5 V, a current of 1.85 mA passes through this solution. Find the specific and equivalent electrical conductivity of the NaNO3 solution.
