Question

please answer question 1

An imaginary element Z has two naturally
occurring isotopes, ³Z and 4Z. ³Z has a mass of
3.016 amu, and "Z has a mass of 4.003 amu. The
atomic mass for the element Z is 3.878 amu.
What is the percent abundance of "Z?
The answer is in %. Do not include units in your
answer. Scientific notation is optional. To write
scientific notation in Canvas, type "e" to replace “x
10". For example, "1 × 1014" is written "1e+14" in
Canvas.
