The atomic mass of copper is 63.55 amu.There are only
two isotopes of copper,63Cu with a mass of 62.93 amu and
65Cu with a mass of 64.93 amu.What is the percentage
abundance of each of these two isotopes?

铜的原子量是63.55 amu.铜只有两个同位素:铜63(质量62.93 amu)和铜65(质量64.93 amu).分别求这两个同位素的百分比含量.
设铜63含量x
63.55=62.93x+64.93(1-x)
解得x=69%
则铜63占69%,铜65占31%
