we calculated the percent of ethanol (v/v) of a beer with the use of fluorescence and raman spectroscopy. The percent of ethanol labeled on the beer was 7.5%, but the value we found through lab was 4.5%. What does this mean exactly? Could we have made a mistake in our lab procedure, or is the label lying. Please explain for full points.
Homework Answers
You calculated the V/V percentage of ethanol in the sample. However the labels are giving you a different term,alcohol proof.
Alcohol proof in UK is defined as 7/4 times the alcohol by volume(ABV).
In US it is defined as twice the percentage of ABV.
Thus both are correct.

A Routine Endoscopic Procedure Our mother usually had an endoscopic procedure every 2 years. We thought that she had too many visits with her gastroenterologist. She saw the gastroenterologist about every 30 or 60 days. When we asked the physician why our mother had to come in on a continuous basis, his response was “acid reflux.” She was taking a proton pump inhibitor for her acid reflux. Our mother had an endoscopy of her upper gastrointestinal tract in September 2006....

The company was counting on tapping the massive potential in emerging markets in order to achieve...

asked each student to estimate his or her score overall, and to
judge their relative rank compared to the other students.
