111. Solving a chemistry problem

Determine the porosity of molecular sieves using experimental data on carbon dioxide sorption at 2560:
Р * 10 -2, N/m2 25 50 100 200 300 500
D 103, kmol/kg 3.64 3.83 3.94 4.1 4.19 4.27
Saturated vapor pressure 23.7 * 105 Pa, molar volume of carbon dioxide 0.0354 m3 / kmol. When calculating, use the Dubinin equation for sorbents of the 1st structural type.
