If light at 193 nm from an argon-fluoride laser is incident on a gold-metal surface, electrons with a kinetic energy of 1.80 *10-19 J are produced.What is the work function of gold in kilojoules per mole? What is the minimum wavelength of light in nanometers required to produce photoelectrons from gold (zero kinetic energy)?
