The molar mass (or molecular weight) is defined as: "The sum of the atomic weight's of all the atoms constituting a molecule; the mass of a molecule relative to the mass of a standard atom, now 12C (taken as 12.000). Relative molecular mass (Mr) is the mass relative to the dalton and has no units." from: ( http://www.books.md/M/dic/molecularweight.php ) Crude Oil consists of a mixture of a lot of different chemical substances, maily hydrocarbons. A molecular mass can -as defined above- only be given for materials that consist of one sort of molecules. till-ga Search strategy: ( ://www.google.de/search?sourceid=navclient&hl=de&ie=UTF-8&oe=UTF-8&q=%22crude+oil%22+properties ) and ( ://www.google.de/search?sourceid=navclient&hl=de&ie=UTF-8&oe=UTF-8&q=%22molar+mass%22+definition ) and personal knowledge as a chemist
