Six grams vegetable oil and a magnetic spinning vane are added to a conical vial. Before attaching a water-cooled reflux condenser to the vial, you will need to add ethanol and 0.20 grams potassium carbonate prior to refluxing your biodiesel synthesis. How many milliliters of ethanol do you need initially to get this reaction started? Assume that the oil requires 3X ethanol in excess per ester group to run a successful reaction. (Average molecular weight per triglyceride molecule of vegetable oil = 990.0 g/mol). Report to 3 sig figs.
