Calculate the monolayer capacity and specific surface area of a sample of silica gel using BET theory. The sample was found to have a weight of 2.56 g and a total surface area of 260 m²/g. The gas used for adsorption was nitrogen at a temperature of 77 K and a pressure range of 0.01-0.3 P/P₀. The plot of (P/P₀)/(V₀/V) versus P/P₀ generated a straight line with a slope of 4.2×10⁻³.
