The number of atoms in a mole, for 10 points, name this constant named after an Italian chemist equal to 6.02 x 1023.
X-ray crystallography can be used to determine this value based on unit cell length, and the namesake of a value similar to it, Josef Loschmidt, expounded the "irreversibility paradox". It is obtained by dividing the Faraday constant by the electron charge, and its namesake hypothesized that equal volumes of ideal gases have the same number of particles.
