Hello all. Can somebody help with this problem and point me in the direction of a website where I can find a TON of practice problems for General Chemistry? Also, what type of problem is this called?

"Certain purple light has a frequency of 4.40 x 10^14 1/s. What is the energy contained in 1.00 mole of these photons?"


Thanks!

Calculate energy of a single photon first, then remember that mole is just an overgrown dozen.
