MOL question

  1. Apr 2, 2008 #1
    Hey guys,

    Just trying to understand this piece of information I have been given. It is for a compression ignition engine.

    I can see where they get the 115.954 kmol/kmol fuel and 120.204 kmol/kmol fuel from but dont understand how to change the units 0.7027 kmol/kg fuel and 0.7285 kmol/kg fuel. They seem to divide kmol/kmol fuel by 165...but dunno why.

    They're converting from kilomoles to kilograms, so they're dividing by the molecular weight of dodecane (165 g/mol).
