Its namesake developed a law stating equal volumes of gas in the same conditions will have the same number of molecules.
Measurements of this constant are based on x-ray diffraction of a crystal silicon lattice. Its namesake developed a law stating equal volumes of gas in the same conditions will have the same number of molecules. Multiplying this constant by the charge of an electron gives Faraday's constant. Multiplying it by Boltzmann's constant gives the gas constant. It was once defined using 12 grams of carbon-12. For 10 points, name this number of atoms in a mole, roughly equal to 6.02 times ten to the twenty-third.
