Question:

M.-G. Olivier and R. Jadot Cl. Chem. Eng. Data 42,230 (1997)) studied the adsorption of butane on silica gel. They report the following amounts of absorption (in moles per kilogram of silica gel) at 303 K:

Fit these data to a Langmuir isotherm, and determine the value of n that corresponds to complete coverage and the constant K.
