Copper has two naturally occurring isotopes, ${ }^{6} \mathrm{Cu}$ (isotopic mass $=62.9296 \mathrm{amu}$ ) and ${ }^{65} \mathrm{Cu}$ (isotopic mass $=64.9278$ amu . If copper has an atomic mass of 63.546 amu, what is the percent abundance of each isotope?
The atomic weight of copper is 63.546 amu. The two naturally occurring isotopes of copper have the following masses: ${ }^{63} \mathrm{Cu}, 62.9298 \mathrm{amu} ;{ }^{65} \mathrm{Cu}, 64.9278$ amu. Calculate the percent of ${ }^{63} \mathrm{Cu}$ in naturally occurring copper.
