Practice Problem ATTEMPT The atomic masses of the two stable isotopes of copper, Cu (69.17 percent) and §Cu (30.83 percent), are 62.929599 and 64.927793 amu, respectively. Calculate the average atomic mass of copper. Practice Problem BUILD The average atomic mass of nitrogen is 14.0067. The atomic masses of the two stable isotopes of nitrogen, "N and N, are 14.003074002 and 15.00010897 amu, respectively. Use this information to determine the percent abundance of each nitrogen isotope. Practice Problem CONCEPTUALIZE The following diagrams show collections of metal spheres. Each collection consists of two or more different types of metal-represented here by different colors. The masses of metal spheres are as follows: white = 2.3575 g, black = 3.4778 g, and blue = 5.1112 g. For each diagram, determine the average mass of a single metal sphere. 000 (i) (ii) (iii)
