Copper has two isotopes, copper-63 and copper-65. It has an atomic mass of 63.546 amu. Sketch a pie graph that shows the approximate abundance of each
copper isotope based on the atomic mass?

69.152 % → 63Cu

30.848 % → 65Cu

Explanation:

As you know, the average atomic mass of an element is determined by taking the weighted average of the atomic masses of its naturally occurring isotopes.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
