Autoimmune Disease List.

There are approximately 602,214,179,300,000,000,000,000 molecules in one mole of any substance (this quantity is called Avogadro's number). Avogadro constant - Wikipedia, the free encyclopedia. The mass of an electron is approximately 0.0000000000000000000000000009109382 grams. Electron rest mass - Wikipedia, the free encyclopedia. Notice these two values are inconvenient to write in regular decimal notation because there are so many digits to write.
In chemistry and physics, the Avogadro constant (named after the scientist Amedeo Avogadro) is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by one mole.
