5. A collector of rare items is negotiating with a museum. He wants to sell a stake he claims to be one that was made to
kill Dracula in the 1400s. A stake size would have started
with around 2 g of carbon-14, and the museum tests show it
now contains around 1g.
a. How many half-lives have passed since the stake was
carved?
b. How long has passed since the stake was carved?
c. Is the stake what the salesman claim?
6. Why is carbon dating not very useful for dating the remains
of dinosaurs?
