Question

What is the wavelength (in nm) of radiation that has an energy content of 3.85 x10^3 kj/mol?

Answer 1

The wavelength (in nm) of radiation that has an energy content of 3.85 x10^3 kJ/mol is 5.16 × 10⁻²³ nm.

Below, how the answer was derived is attached;  note that C = speed of light, λ= wavelength, E= energy & h = Plank's Constant.
