Station __: If we start with 120 atoms of a radioactive substance, how many will remain after 5 half lives. Show your work.

3
3.75 atoms

4
Station __: When you analyze a rock sample you find that only 6.25% of the original Carbon-14 remains. Knowing that Carbon-14 has a half life of 5,730 years, how old is the rock approximately? Show your work.

5
22,920 years

6
Station __: If a sample know to be about 11,460 years old has 400 Carbon-14 atoms, how many atoms were in the sample when the organism died? The half life of Carbon-14 is 5,730 years. Show your work.

Station __: Sodium-24 has a half-life of 15 hours. How much sodium-24 will remain in an 18.0 g sample after 60 hours? Show your work.

9
1.125 GRAMS

10
Station __: After 42 days a 2.0 g sample of Phosphorus-32 contains only .25 g of the isotope. What is the half-life of phosphorus-32? Show your work.

11
14 Days

12
Station __: Polonium-214 has a relatively short half-life of 164 seconds. How many seconds would it take for 8.0 g of this isotope to decay to .25 g? Show your work.

13
820 secs

14
Station __: How many half-lives does it take for 16 g of Palladium-103 to decay to 1.0 g? Show your work.

15
4 half lives

16
Station __: What percentage of the original sample of Copper-66 would remain after 51 minutes if the half-life is 5.10 minutes? Show your work.

17
.1 %

18
Station __: In 5.49 seconds, 1.20 g of Argon-35 decays to leave only 0.15 g. What is the half life of Argon-35? Show your work.

23
74.88 days

24
Station __: The half-life of Cobalt-60 is 5.26 years. If 25 grams are left after years, how many grams were in the original sample? Show your work

25
3200 grams

26
