Problem 106P

Copper has two naturally occurring isotopes. Cu-63 has a mass of 62.939 amu and relative abundance of 69.17%. Use the atomic weight of copper to determine the mass of the other copper isotope.

Step-by-Step Solution:

 

Step 1</p>

 

To calculate the atomic weight, the atomic weight of each isotope is multiplied by its percent abundance (expressed as a decimal). Then the results are added together.

 

i.e. atomic mass=sum of ((isotopic abundance) (atomic mass)-----(1)

Atomic mass of the element copper = 63.5amu

Atomic mass of first isotope=62.939amu                        

Relative abundance=69.17%

                 

Relative abundance of second isotope=100-69.17=30.83%

Atomic mass of second...
