93. Solving a chemistry problem

219. The number of moles of a solute adsorbed per gram of a solid adsorbent was determined by measuring the change in concentration in a solution as a result of adsorption at a constant temperature. The following table shows this data as a function of solute concentration
s, mol/l 0.75 1.40 2.25 3.00 3.50 4.25
n*104, mol 6.03 7.84 9.57 10.0 10.4 10.8

Determine the Langmuir adsorption isotherm coefficients. If the specific surface area of ​​the adsorbent is 325 m2/g, then what is the area occupied by an adsorbate molecule in a saturated monomolecular layer ?
