What is the energy per mole of photons of light with a wavelength of 690.8 nm? A) 2.88 × 10^-19 kJ/mol B) 4.16 × 10¹⁴ kJ/mol C) 2.61 × 10³⁵ kJ/mol D) 4.34 × 10¹⁴ kJ/mol E) 1.73 × 10² kJ/mol

Question

Quizplus · Accepted Answer

The energy of a photon is calculated using E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength. Converting the energy from joules to kJ/mol gives approximately 1.73 × 10^2 kJ/mol.
