Can E=hv be used to calculate the energy required to remove an electron?

The formula can be used to find the energy of light of a given frequency.

The equation spelled out is "energy = planck's constant x wavelenght", and since you want to find energy, this equation would be perfect, that is, if you are using it in the correct context.

In this case, the equation says that the energy of a particle of light is proportional to its frequency by a constant factor. Therefore, this equation can be used to calculate the energy required to remove an electron.
