Ozone, O 3 , absorbs ultraviolet radiation and dissociates into O 2 molecules and O atoms: O

Question:

Ozone, O₃, absorbs ultraviolet radiation and dissociates into O₂ molecules and O atoms: O₃ + hν → O₂ + O. A 1.00 L sample of air at 22 °C and 748 mmHg contains 0.25 ppm of O₃. How much energy, in joules, must be absorbed if O₃ all the molecules in the sample of air are to dissociate? Assume that each photon absorbed causes one O₃ molecule to dissociate, and that the wavelength of the radiation is 254 nm.
