85. Solving a chemistry problem

216. The adsorption of polystyrene with a molar mass of 300 kg/mol from toluene on activated carbon with a specific surface area of 120 m2/g was studied. Adsorption was found to follow the Langmuir equation with an adsorption capacity of 33 mg of polymer per gram of adsorbent. At a concentration of 0.1 g/L, adsorption was 28 mg/g. Calculate the Langmuir adsorption constant and the number of adsorbed polymer molecules per 1 m2 of coal surface, with a saturated adsorption capacity.
