Endometriosis is a condition that causes endometrial tissue to grow outside of the uterus. This tissue can be found in patches on the surface of the ovaries, bladder, colon and abdomen.
It refers to the fact that the bottles were 1/5th of a gallon. These days most bottles are 750 ml, which is close to 1/5 of a gallon. A gallon contains 128 fluid ounces. So a fifth (1/5) or 750ml contains a tad more than 25 oz, or 25 one-ounce shots. Of course, many use 1 Â½ ounce for a standard shot which is around 16 shots. Bar Measurement Chart.
Close but a little off. You can round it to 17 shots in a fifth. A standard shot is indeed 1.5 ounces, and a fifth is 750 millileters. There are 44.36 mL in each 1.5 oz shot. doing the math, there are 16.907 1.5oz shots in a fifth. Not off by much really, but the extra mil and a half would be nice :)
