46. Solving a chemistry problem

4. Calculate the thickness of the diffuse ion layer λ on the plate surface at 300 K in an aqueous solution, 1 liter of which contains 0.05 g NaCl and 0.01 g Ba(NO3)2 (indifferent electrolytes). The relative permittivity of the solution is 76.5. How many times will λ change if the solution is diluted 4 times with deionized water?
