What information about these isotopes is needed to determine titanium’s average atomic mass?

To determine the average atomic mass of titanium, you need the following information about its isotopes:

1. The different isotopes of titanium: Titanium has five naturally occurring isotopes, which are Ti-46, Ti-47, Ti-48, Ti-49, and Ti-50.

2. The atomic mass of each isotope: Each isotope of titanium has a different atomic mass. For example, the atomic mass of Ti-48 is 47.94795 amu.

3. The natural abundance of each isotope: This is the percentage of each isotope found in nature. For example, Ti-48 makes up about 73.8% of all naturally occurring titanium.

With this information, you can calculate the average atomic mass of titanium by multiplying the atomic mass of each isotope by its natural abundance (as a decimal), and then adding up these products.
