Could somebody please help me to convert these units? (Parts to Moles)


I'm reading an old document that refers to its units as parts and I'm unsure how to convert these to moles/grams/ml

It speaks about 106 parts ethanol, 2 parts glacial acetic acid, 5 parts catalyst etc, etc...

Would anyone be able to clarify this?

You have a recipe with "parts" -- which basically boils down to a ratio -- presumably a ratio by mass. (Ratio by volume is also possible if all quantities are liquids -- which is what happens in cocktail recipes.)


Unfortunately,you cannot convert this to a specific mass since no mass information is given.
You can specify your own total mass and then use the ratio to work out a mass for each component. Then convert to moles at your leisure.
