Question

It takes 497 kJ to remove one mole of electrons from the atoms at the surface of a solid metal.

What is the maximum wavelength of light capable of doing this?

Answer 1

Waaaaaaaaaaaaaay to much

Answer 2

375 nm

Step-by-step explanation:

The maximum wavelength of light capable of removing one mole of electrons from the atoms at the surface of a solid metal can be calculated using the equation E=hc/λ, where E is the energy required to remove the electrons, h is the Planck constant, c is the speed of light, and λ is the wavelength of the light.

Substituting the values, we get:

E = hc/λ497 kJ = (6.62 x 10^-34 Js) (3 x 10^8 m/s) / λ

Rearranging the equation and solving for λ, we get:λ = (6.62 x 10^-34 Js) (3 x 10^8 m/s) / 497 kJλ = 3.75 x 10^-7 m or 375 nm.

Therefore, the maximum wavelength of light capable of removing one mole of electrons from the atoms at the surface of a solid metal is 375 nm
