Calculate the energy (in J) for one mole of photons that have a wavelength of 5.461 x 10 2 nm. Choose one answer. A. 2.437 x 10-12 J B. 2.191 x 10-4 J C. 2.191 x 105 J D. 1.376 x 106 J . we know that E = h*c/lamda Where, E=energy, h is planck's constant, and c is the speed of light in a vacuum. 1 mol = 6.022*10^23 so, E=(6.63*10^-34 J/s * 3.0*10^8) / (5.46*10^ -7) For 1 mole E= (6.63*10^-34 J/s * 3.0*10^8) / (5.46*10^ -7)*6.022*10^23= 2.191 x 10-4 J . Answer is B.2.191 x 10-4 J
