128. Solving a chemistry problem

1.59. Table 1.6 shows the dependence of surface tension on the concentration of surfactant solutions. Determine the area occupied by a surfactant molecule in a saturated adsorption layer and the thickness of the adsorption layer. The surfactant density is considered equal to p = 0.95 g/cm3.
