(Q1) How to specify molecular weight for a mixture: (1) use molar proportional average MW or (2) add both MWs together? PCDmanager uses Method 2. Is there a problem using an average MW of 142.321 (Method 1) vs UNIFAC MW of 296.234 (Method 2)? Will this affect property estimates using UNIFAC? Molar to mass conversion? How to resolve?
(Q2) The <Component> panel calculates a Method 2 MW and gives a red-flagged preferred data check on the Formula. Can this flag be cleared or should it just be ignored?
(Q3) After configuring UNIFAC, the UNIFAC LLE and ASOG panels are automatically populated, but with the wrong functional groups. This occurs after clicking the <Generate all missing data from UNIFAC> Button.
