Final answer:
The average atomic mass of 5f titanium on the planet can be calculated based on the isotopic abundances.
Step-by-step explanation:
The average atomic mass of 5f titanium on the planet can be determined by considering the isotopes present on that planet and their abundance. Isotopes are atoms of the same element with different numbers of neutrons. The average atomic mass is the weighted average of the atomic masses of all the isotopes, where the weights are the relative abundances of each isotope. For example, if there are two isotopes of titanium on the planet, one with an atomic mass of 48 and abundance of 70%, and another with an atomic mass of 50 and abundance of 30%, the average atomic mass can be calculated as follows:
(48 x 0.70) + (50 x 0.30) = 48.4 atomic mass units (amu)
