it was observed that electrons were released with

It was observed that electrons were released with a kinetic energy(KE) of 3.50× 10^(-19) Joules When a metal was exposed to light at 3.09× 1015 s^(-1) of frequency,. Determine the maximum number of electrons that could be emitted from metal by a burst of light with a total energy (E)of 9.86× 10^(-7) Joules?
