5. Element X has two isotopes: X-100 and X-104. If the atomic mass of X is 101
amu, what is the relative abundance of each isotope in nature?


Sagot :

Answer:

The abundance of X-100 is 75 percent, and X-104 has an abundance of 25 percent. The answers are found by solving two equations with two unknowns, which are A plus B equals 100, and 100A plus 104B equals 10,100.
