Question

One type of sunburn occurs on exposure to UV light of wave lengthin 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 1.00mJ burst of thisradiation?

d.) These UV photons can break chemical bonds in you skin tocause sunburn~a form of radiation damage. If the 325 nm radiationprovides exactly the energy to break an average chemical bond inthe skin, estimate the average energy of these bonds inkJ/mol.
