Web5 jun. 2024 · Hence, the energy PER PHOTON is simply: E = 6.626 ×10−34J ⋅ s ⋅ 2.998 × 108 m / s 4 × 10−7m. = 4.97 ×10−19J/photon. But this number is clunky... since we want the MOLAR photon energy, 4.97 ×10−19 J photon × 6.0221413 × 1023 photons 1 mol × 1 kJ 1000J. = 299.07 kJ/mol. But since you only gave 1 sig fig, I can only report 300 ... WebThe mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon 12. Avogadro's number (Equation ) like any pure number, is dimensionless. However, it also defines the mole, so we can also express NA as 6.02 × 1023 mol–1; in this form, it is properly known as Avogadro's ...
