A student wants to determine the specific surface area of a solid sample using gas adsorption. The sample has a mass of 1 gram and the adsorption isotherm follows the BET model. The student measures the volume of nitrogen gas adsorbed at different pressures and obtains the following data:Pressure (torr) | Volume of nitrogen (cm3)---------------|----------------------- 50 | 24.51 100 | 39.22 200 | 67.38 300 | 90.86 400 | 104.29What is the specific surface area of the sample based on the BET model?
