Welcome to PhilosFX, the blog that asks, "If your life were a movie, would anyone watch?" We'll combine philosophy and special effects to explore a wide range of subjects. Some call it, "Technicolor Omphaloskepsis." I call it Life: examined, shared, and truly lived.
Today is Mole Day! Celebrated annually on October 23 from 6:02 a.m. to 6:02 p.m., Mole Day commemorates Avogadro's Number (6.02 x 10^23), which is a basic measuring unit in chemistry.
For a given molecule, one mole is a mass (in grams) whose number is equal to the atomic mass of the molecule. For example, the water molecule has an atomic mass of 18, therefore one mole of water weighs 18 grams. In general, one mole of any substance contains Avogadro's Number of molecules or atoms of that substance.
