What is the energy of a mole of photons with a frequency of 2.9 * 10¹⁵ sec^-1? A) 1.2 * 10⁶J/mol B) 1.2 * 10⁹J/mol C) 8.3 * 10^-7J/mol D) 8.3 * 10⁷J/mol E) 6.7 * 10⁶J/mol

Question

Quizplus · Accepted Answer

The energy of a mole of photons can be calculated using the formula E = N_A * h * ν, where N_A is Avogadro's number (6.022 × 10^23 mol^-1), h is Planck's constant (6.626 × 10^-34 J·s), and ν is the frequency of the photons. Given the frequency, the correct energy value can be calculated, and option A provides a plausible numerical value consistent with the expected magnitude for the energy of a mole of photons at the given frequency.
