a & b
4. Some photosynthetic bacteria are able to harvest 800 nanometer light. A. What is the energy in kilocalories (or kilojoules) of a mole (einstein) of 800 nm light? Use shortcut. Just set up the problem, or answer by long division. Include all units in your answer! (4)
B. What is the energy in kilocalories of one photon of 800 nm light? Just set up the problem, but please include units in your answer! [kcal, cal, Joules, or kJ/photon would be ok]. Two different formulae can be used to answer this question.
