If the half-life of carbon-14 is about 5,700 years,then of a given starting quantity,after 22,800 years (four half-lives),what fraction of the original amount will be left?

Question

Quizplus · Accepted Answer

Each half-life of carbon-14 reduces the amount of carbon-14 to half of its original value. After 4 half-lives (22,800 years), the fraction of the original amount remaining would be (1/2)^4 = 1/16. Therefore, the correct answer is option D, 1/16.
