Chapter 9, Problem 110E

The particle nature of light was first proposed by Albert Einstein, who suggested that light could be described as stream of particles called photons. A photon of wavelength I has an energy (E) given by the equation: $E=hc/\lambda$

where E is the energy of the energy of the photon in j, h is Planck’s constant $\left(6.626\times {10}^{-34}\text{J}\text{.s}\right)$, and c is the speed of light $\left(3.00\times {10}^8\text{m}/\text{s}\right).$

Calculate the energy of 1 mol of photons with a wavelength of 632 nm.
