Answer 1

The relative abundance of an isotope is the percentage of atoms with a specific atomic mass found in a naturally occurring sample of an element.

Answer 2

Answer:

Since x = 0.996, multiply by 100 to get percent: nitrogen-14 is 99.6%. Since (1-x) = (1 - 0.996) = 0.004, multiply by 100: nitrogen-15 is 0.4%. The abundance of the nitrogen-14 isotope is 99.6 percent, and the abundance of the nitrogen-15 isotope is 0.4 percent.
