Calculate the enthalpy of adsorption for the adsorption of 5 grams of hydrogen gas on a solid adsorbent at a temperature of 298 K, if the pressure of hydrogen gas is 2.5 atm and the volume of the adsorbent is 100 cm3. Assume ideal gas behavior and use the equation ΔH = -q/n, where ΔH is the enthalpy of adsorption, q is the heat absorbed, and n is the number of moles of gas adsorbed.
