**Photodissociation of Hydrogen Molecules**Light of wavelengths shorter than 275 nm can be used to photodissociate hydrogen molecules into hydrogen atoms in the gas phase. In this scenario, a 70.0 mL glass cylinder contains \( \text{H}_2 (g) \) at 65.0 mtorr and 25 °C. **Problem:**What is the minimum amount of light energy that must be absorbed by the hydrogen in the tube to dissociate 26.0% of the molecules?**Solution Attempt:**An energy value of 0.277 J was entered, but it is labeled as "Incorrect."**Instructions:**Use the principles of photochemistry and gaseous equilibrium to calculate the correct amount of energy needed for the dissociation process. Remember to convert pressure and volume units, and consider the dissociation energy per molecule to find the total energy required.
