The Bowers-Davis experiment attempted to calculate it by finding the constant of proportionality between a quantity determined in the Millikan oil-drop experiment and the Faraday constant; it also provides the conversion factor between the Boltzmann constant and the ideal gas constant.
It is typically computed using x-ray crystallography and a tiny cube of silicon, while it was given its current name and calculated using Brownian motion by Jean-Baptiste Perrin.

For 10 points, identify this large constant, whose namesake reached his best-known conclusion after observing that the volume of gas evolved by electrolysis obeyed the reaction's stoichiometry, which gives the standard volume of a gas, twenty-two point four liters, at standard temperature and pressure, and which is the conversion factor between grams and atomic mass units, the number of particles in a mole.
