Question

The average atomic mass of copper is 63.5amu. If the only two isotopes of copper have mass numbers 63 and 65 calculate the percentage abundance of each isotope

Answer 1

Explanation:

Copper has two naturally occurring isotopes: copper-63 (69.17%) and copper-65 (30.83%). Calculate the average atomic mass of copper if the relative masses of the isotope are copper 63 (62.93 amu) and copper-65 (64.93 amu
