for "back of the envelope" accuracy, whether fat or oil, to two significant digits one can estimate the molecular wt of the oil to be about 900 (slightly high) and the density is about .9 so the fat/oil contains about one mole per liter, therefore one mole of glycerin is present. The molecular wt is 94 so you would get about 94 grams of glycerin from a liter of fat/oil. The density is about 1 so you would get about 94 ml per liter of oil.
