Question 1

An archeological artifact was subjected to radiocarbon dating. The artifact showed a carbon-14 decay rate of 13.8 disintegrations/min per gram of carbon. Carbon-14 has a half-life of 5715 years, and currently living organisms decay at the rate of 15.3 disintegrations/min per gram of carbon.  What is the approximate age of the artifact?
◦ 257 years old
◦ 591 years old
◦ 371 years old
◦ 851 years old

Question 2

The ratio of 238U to 206Pb is used to date old mineral samples. Each 1.000 g of 238U that decays eventually produces 0.866 g of 206Pb. If the half-life of 238U is 4.468 × 109 years, what is the age of a mineral that has a 238U/206Pb mass ratio of 2.00?
◦ 3.87 × 109 years
◦ 4.47 × 109 years
◦ 2.94 × 109 years
◦ 3.60 × 109 years
