The formula C23H20 describes a molecule made of 23 carbon atoms and 20 hydrogen atoms. It is written in Hill notation: carbon first, then hydrogen, then the other elements in alphabetical order. The formula tells you which atoms are present, not how they are connected, which is why several different chemicals can share it.

Elemental composition

  • C Carbon × 2393.20%
    12.011 × 23 = 276.253 g/mol
  • H Hydrogen × 206.80%
    1.008 × 20 = 20.160 g/mol
