Problem 27E

Quantized Energy and Photons (Section)

One type of sunburn occurs on exposure to UV light of wavelength in the vicinity of 325 nm.

(a) What is the energy of a photon of this wavelength?

(b) What is the energy of a mole of these photons?

(c) How many photons are in a 1.00 mJ burst of this radiation?

(d) These UV photons can break chemical bonds in your skin to cause sunburn—a form of radiation damage. If the 325-nm radiation provides exactly the energy to break an average chemical bond in the skin, estimate the average energy of these bonds in kJ/mol.
