work function given in kJ*mol^-1

Postby Emely Reyna 1F » Sun Apr 15, 2018 10:03 pm

If the work function is given in kJ*mol^-1 how would i get rid of the mol^-1 since the units are suppose to be in just J?

Hello!

You should divide the work function by Avogadro's number to get rid of the mol^-1.

The work function of the metal you use in the photoelectric equation from class is related to per 1 photon. 1 photon will interact with 1 atom, so you will have to convert the value in terms of per atom in order to use the photoelectric equation.
