Question
**Photoelectric Effect Problem**

It takes 254 kJ/mol to eject electrons from a certain metal surface. What is the longest wavelength of light (in nm) that can be used to eject electrons from the surface of this metal via the photoelectric effect? (Planck's constant, *h* = 6.626 x 10⁻³⁴ Js)

**Options:**
- 725 nm
- 471 nm
- 165 nm
- 233 nm

This problem involves calculating the maximum wavelength of light that can overcome the work function (energy required to remove an electron) of a metal, which is provided in energy per mole. You will need to convert this energy into energy per photon using Avogadro's number, and then apply the photoelectric equation to find the wavelength.
