Calculte the Energy of 1 mole of photons - Help!!! 1. The problem statement, all variables and given/known data Calculate the energy, in kilojoules, of one mole of photons of yellow laser light of wavelength 570 nm. The correct answer is: 2.10x102 2. Relevant equations Ephoton= hc/wavelength 3. The attempt at a solution Step by step: 1. Convert the wavelength of 570nm to m: 10-9m= 1 nm, so: 570nm * (10-9m) = 5.7E-7 m 2. Ephoton= hc/wavelength Ephoton= (6.63E-34 * 3.E8)/5.7E-7 m Ephoton= 3.49E-19 J 3. Finally, I convert to kJ: Ephoton= 3.49E-19J/1000J = 3.49E-22 kJ Can someone help me with this problem, I tried many times but I still get the same result.
