Corelation For Molecular Weight - Industrial Professionals ...

Dec 14, 2008 Corelation For Molecular Weight - posted in Industrial Professionals: I have ASTM D-86 distillation data for Naphtha. Weight percentages of Paraffins, Naphthenes, Aromatics are also known. Sp Gr. is also known. I would like to know its molecular weight. Is there any way to calculate its molecular weight from the above data.Thanks
