A 1.00-L sample of air at 22oC and 748 mmHg contains 0.25 ppm of O3. How much energy, in joules,
must be absorbed if all the O3 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.
