WebThe energy of a photon can be calculated from Planck's equation, by multiplying the photon frequency by Planck's constant. Due to the property of photons which relates wavelength to frequency by the constant speed of light, we can set up a simple photon energy calculator in the form of an equation. The mole (symbol mol) is the unit of amount of substance in the International System of Units (SI). The quantity amount of substance is a measure of how many elementary entities of a given substance are in an object or sample. The mole is defined as exactly 6.02214076×10 elementary entities.
