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.

Calculate the heat of hydration for the reaction between anhydrous copper sulfate (CuSO4) and water (H2O), given that the mass of anhydrous copper sulfate used is 10 g and the temperature of the solution increases from 25°C to 35°C. The molar heat of hydration for copper sulfate pentahydrate (CuSO4.5H2O) is -90.1 kJ/mol.
