FREE Expert Solution

We´re asked to determine the energy (in kJ) of 3.00 moles of photons and a wavelength of 675 nm.


Remember that the Energy and the frequency of a photon are related by the following equation:

E=

Where

E is the energy of the photon (in J)

h is the Planck’s constant (h = 6.626x10-34 J*s)

ν is the frequency of the photon (in s-1)
