Photon Energy Problem

[McMaster_Girl]

What is the energy carried by a mole of photons of wavelength 522nm which is associated with green light?

[Repetit]

Find the energy carried by one photon and multiply by Avogadro's number.

In terms of frequency the energy carried by a photon is:


E=h \nu


Where h is Planck's constant and \nu is the frequency. So you have to express the frequency through the wavelength.
