Consider a solution of gas X in contact with a solid surface at a constant temperature. The Langmuir adsorption isotherm for this system is represented by the equation /= _/(1+), where is the partial pressure of gas X, is the volume of the gas, _ is the saturation pressure of the gas, and is the Langmuir adsorption constant. Suppose a student conducts an experiment to investigate the Langmuir adsorption isotherm for gas X on a particular solid surface. They measure the partial pressure of the gas at various volumes and obtain the following results: (mL/g) : 2.0 2.5 3.0 3.5 4.0 (atm) : 0.2 0.4 0.6 0.8 1.0 Using these values, what is the Langmuir adsorption constant, , for the given system?
