118. Solving a chemistry problem

Calculate the potential energy and interactions of two plane-parallel plates in an aqueous electrolyte solution with concentration c, at the diffuse layer potential φδ, relative permittivity εr, and temperature t. When calculating, take the Hamaker constant A* = 3.0*10-20 J. Make calculations for the distances between the plates h: 2, 5, 10, 15, 25, 50 nm. Build a dependency graph u=f(h).
