Estimating the size of a molecule using oil. It would be wonderful if you could measure the size of a single atom, but atoms are so small that it cannot be done directly. Yet you can find the size of a molecule in a roundabout way and from that calculate the size of an atom. Lord Rayleigh (English physicist, 1842 to 1919.
Example: A single 12C atom has a mass of 12 amu, and a mole of these atoms would have a mass of 12 grams. A mole of any atoms has a mass in grams equal to the atomic weight of the element. The term mole can be applied to any particle: atoms, a mole of atoms, a mole of ions, a mole of electrons, or a mole of molecules.
