What is the energy in joules of a mole of photons associated with visible light of wavelength 486 nm? (c = 3.00 × 10⁸m/s; h = 6.63 × 10^-34 J • s; N_A = 6.022 × 10²³ moles^-1) A) 6.46 × 10^-16 J B) 6.46 × 10^-25 J C) 2.46 × 10^-4 J D) 12.4 kJ E) 246 kJ

Question

Quizplus · Accepted Answer

The energy of one photon is calculated using E = hc/λ. For a mole of photons, multiply by Avogadro's number (N_A). This results in approximately 246 kJ.
