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.
Hydrogen has an atomic mass unit of 1 so a mole of hydrogen measures 1 gram. It is common in molecular biology to use units of moles and molarity. It is important to distinguish the unit of mass (moles) from the unit of concentration (molarity). Moles are simply a unit of mass and are abbreviated as mol. Molarity is designated by an upper case âMâ and is defined as moles per liter.
