Explanation:
The half life of a certain substance is being used to date fossils or to know their age. Most likely, it is carbon-14 that is the substance that is being traced in fossils since it is what remains after million of years in a fossil. The half life is important in determining the constant in the decay and, consequently, determining the age of the fossil.
Answer:

Explanation:
To do this, we find the moles of each element. We get around 0.155 moles of Fe, 0.051 moles of P, and 0.206 moles of O. We then divide each one by the smallest one (which is 0.051 moles of P). We then get 3 for Fe, 1 for P, and 4 for O. This correlates to the empirical formula of the compound.
