Barium – 122 has a half-life of 2 minutes. Suppose you obtain a sample weighing 100.0 g and it takes 14 minutes to set up an experiment. How many grams of Barium – 122 will remain at the point when you begin the experiment?
Added by John M.
Step 1
Given that the half-life of Barium-122 is 2 minutes, we can calculate the number of half-lives as follows: Number of half-lives = 14 minutes / 2 minutes per half-life Number of half-lives = 7 Show more…

Barium-122 has a half-life of 2 minutes. Suppose you obtained a sample weighing 12.4 g and it takes 10 minutes to set up an experiment in which the barium-122 is to be used. How many grams of barium-122 will remain at the point when you begin the experiment?

Barium – 122 has a half-life of 2 minutes. Suppose you obtain a sample weighing 20.0 g and it takes 10 minutes to set up an experiment. How many grams of Barium – 122 will remain at the point when you begin the experiment? Do not enter the unit (which is understood to be "grams"). If you enter a unit explicitly (such a "g"), your answer will be counted wrong.

The half-life of $\frac{208}{81} \mathrm{Tl}$ is 3.1 minutes. A 84.6 -gram sample is studied in the laboratory. a) How many grams of the isotope will remain after 12 minutes? b) In how many minutes will the mass of $^{208}$ TI be 3.48 grams?
