79. Solving a chemistry problem

87. Calculate the rate of electroosmosis of a solution of 5 mmol / l KCl through porous corundum, if the zeta potential is known, determined by the rate of electrophoresis of corundum particles in the same solution, 70 mV. Solution viscosity 0.890*10-3 Pa*s, relative permittivity 78.4; electric current strength 2.13 * 10-2A. The molar electrical conductivity of the solution is known to be 1.435*10-2 Sm*m2*mol-1.
