Express your answer in joules to three significant figures. b) What is the energy of a mole of these photons? Express your answer in joules per mole to three significant figures. c) How many photons are in a 1.10 mJ burst of this radiation? Express the number of photons to three significant figures. d) These UV photons can break chemical bonds in your skin to cause sunburn (a form of radiation damage). If the 310 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. Express your answer in kilojoules per mole to three significant figures.
