A chemistry student is investigating the surface area of activated carbon for an adsorption experiment. Using BET theory of multilayer adsorption, determine the specific surface area of the activated carbon based on the following data: - Mass of activated carbon used: 0.25g- Nitrogen adsorption at various pressures (in mmHg): - 6.523 - 9.785 - 13.092 - 19.638 - 31.725 - 45.200 - 61.587 - 84.632 - 114.684 - 147.087 Assume that the area occupied by one nitrogen molecule is 0.162 nm², and use the BET equation to calculate the specific surface area of the activated carbon material.
