One type of sunburn occurs on exposure to UVlight of wavelength (λ) in the vicinity of 290 nm. What is the energy of a mole of these photons in kJ/mol? Given c = λν, E = hν, the speed of light (c) is 2.99 x 108m/sec, 1 nm = 1.0 x 10-9 m, Planck’s constant is 6.626 x 10-34 J/sec and a mole = 6.022 x 1023 photons.
