A wooden boat discovered just south of the Great Pyramid in Egypt as a carbon-14 / carbon -12 ratio that is 72.5% of that found in currently living organisms. How old is the boat?
Homework Answers
carbon half life = 5730 yrs
decay constant = 0.693 / half life = 0.693 /5730 = 1.209 x 10^-4 yrs-1
A = 100 %
At = 72.5 %
t = 1/ K * ln (A/At)
t = 1/ (1.209 x 10^-4) * ln (100/72.5)
t = 2660 yrs
boat age = 2660 yrs

7.2.47 The half-life of carbon-14 is 5730 years. A frozen human mummy was discovered in a glacier. It was estimated that this human died 5100 years before he was discovered in the melting glacier. How much of the original carbon-14 remained in the mummy at the time of his discovery? The frozen human has about % of the carbon-14 expected in living matter.

An archeological artifact was subjected to radiocarbon dating. The artifact showed a carbon-14 decay rate of 12.2disintegrations/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? Select one: A. 371 years old B. 6597 years old C. 851 years old D. 1867 years old

Carbon 14 is a radioactive isotope produced in the upper atmosphere by cosmic rays. It has a half-life measured as 5730 : 40 years. Since plants and animals absorb carbon from the atmosphere, the percentage of carbon a living organism contains that is carbon 14 is equal to the percentage of carbon 14 in the atmosphere. When an organism dies, however (or when a layer of wood is laid down as bark in a tree), it ceases to absorb carbon....
