WebAvogadro's number, N A, is defined as the number of atoms in 12 gram of carbon-12 atoms in their ground state at rest.By definition it is related to the atomic mass constant m u by the relation . The exact factor 1/1000 appears here by the historic facts that the kilogram is the unit of mass and that in chemistry the mole is preferred over the kmole. The atomic … Web20 de ago. de 2011 · The first estimate of Avogadro's number was made by a monk named Chrysostomus Magnenus in 1646. He burned a grain of incense in an abandoned church and assumed that there was one 'atom' of incense in his nose at soon as he could faintly smell it; He then compared the volume of the cavity of his nose with the volume of … list of steampunk movies
