QUESTION:

Ancient Meat Eating. The amount of meat in prehistoric diets can be determined by measuring the ratio of the isotopes nitrogen-15 to nitrogen-14 in bone from human remains. Carnivores concentrate 15N, so this ratio tells archaeologists how much meat was consumed by ancient people. Use the spectrometer of Exercise 27.34 to find the separation of the 14N and 15N isotopes at the detector. The measured masses of these isotopes are ( 14N) and (15N).
