What is the energy of a mole of photons with a frequency of 3.8 * 10¹⁴ /sec? A) 1.5 * 10⁵J/mol B) 1.5 *10^-5J/mol C) 6.7 * 10^-7J/mol D) 6.7 * 10⁷J/mol E) 3.8 * 10^-5J/mol

Question

Quizplus · Accepted Answer

The energy of a mole of photons can be calculated using the equation E = N * h * ν, where N is Avogadro's number (6.022 x 10^23 mol^-1), h is Planck's constant (6.626 x 10^-34 J·s), and ν is the frequency of the photons. Given the frequency (3.8 x 10^14 /sec), the calculation yields an energy value close to 1.5 x 10^5 J/mol, making option A the correct choice.
