![1. The following data refer to the adsorption of butane at 0°C onto tungsten powder (area 16.7 m²
g¹). Determine whether the data can be fitted with the Langmuir isotherm. If yes, then calculate
the number of moles adsorbed in a monolayer, and hence the molecular area for the adsorbed
butane (at monolayer coverage); and compare it with the value of 32 x10-20 m² estimated from
the density of liquid butane.
