Photons and E=hv

What is the relationship between number of photons and energy in the equation E=hv? Do you multiply E by number of photons?

E=hv is used for energy of 1 photon. If you wanted to find the energy of a mol of photons, then you would multiply by Avogadro's Number.

E=hv is the same as Energy(photon) = to hv, in other words, it is proportionate to the frequency.

You have to multiply it by Avogadro's number which is 6.022 x 10^23. This will give you the number of photons

E gives the energy of one photon, v is frequency, and h is planck's constant.
