Explanation:
Hello there!
In this case, since the radioactive decay is considered as first-order kinetic model, whereby the remaining mass of the radioactive material involves the initial one, the rate constant and elapsed time:
As we were not initially given the rate constant, we can use the half-life to calculate it as follows:
Thus, we can calculated the elapsed time for the given conditions to obtain:

The element symbol for Thallium is TI.
They have text books with periodic tables in them if you need extra help.
Hope this works out for ya.

Explanation:
Hello,
In this case, by knowing the volume and the molarity of the barium iodide, is it possible to compute the residue's mass as shown below:
Nevertheless, the obtained value is lower than the obtained by 6.133 g which means that mass corresponds to water forming a hydrate. In such a way, one could know how many waters in form of hydrate remain with the residue by a trial-error procedure as shown below:
Therefore, the formula is barium iodide hexahydrate:
Best regards.
