At 0°C and I atm pressure, the volume ol nitrogen gas required to cover a sample of silica gel, assuming Langmuir monolayer adsorption, is found to be 130 cm g of the gel. Calculate the surface area per gram of silica gel Given that the area occupied by a nitrogen molecule is 0.162 (nm) SA0amd afuatan edo
