3 A twig from a bristlecone pine tree is found in a sedimentary layer, and its age is to be determined. The twig is a 7.0-gram piece of cellulose (C6H10O5: molar mass = 162 g/mole). This specimen is taken and placed between scintillation detectors, and over a 24-hour period 26,500 decays were recorded. How old is this twig? Assume that when the tree was living, carbon-14 accounted for 1 out of every 7.2x1011 atoms of carbon. The half-life of carbon-14 is 5730 years.

The ratio of C-14 to C-12 in a piece of wood from an archeological site was found to be only 0.354 of what it is in a piece of wood taken from a tree today. In years, what is the age of the wood based on this C-14 measurement? The half-life of C-14 is 5730 years. Provide answer rounded to the nearest year but do not put units in the answer box.

The cloth shroud from around a mummy is found to have a 14C14C activity of 8.7 disintegrations per minute per gram of carbon as compared with living organisms that undergo 16.3 disintegrations per minute per gram of carbon. From the half-life for 14C14C decay, 5715 yryr, calculate the age of the shroud. Express your answer using two significant figures.
A sample of bone is subjected to radiocarbon dating. The current decay rate observed for its carbon-14 content is 11.2 disintegrations per minute per gram of carbon. What is the age (in years) of the bone? The half-life for carbon-14 is 5.73 x 103 yrs, and the decay rate for carbon-14 in living organisms is 14.3 disintegrations per minute per gram of carbon.
Archeologists continue to debate the arrival of the first humans in the Western Hemisphere. Radiocarbon dating of charcoal from a cave in Chile was used to establish the earliest date of human habitation in South America as 8700 years ago. This procedure involves comparing the 14C present in a sample of charcoal to the 14C present in a living tree of the same age. What fraction of the 14C initially present remained in the charcoal after 8700 years? The half-life of 14C is 5730 years. (Write the answer as a number with a decimal.)
The half-life of 14C is 5730 years, and the current decay rate in living organisms is 14.3 disintegrations per minute per gram of carbon (d.p.m./g C). What is the age (in years BP) of an artifact found to have a decay rate of 4.75 d.p.m/g C in 2013? IMPORTANT: When entering your answer: • Enter the number only (no units) • Do not leave any spaces • Report your number to the tens column (regardless of the significant figures) Correctly round your answer to the tens column (margin of allowed error is only ± 10, so always use un-rounded numbers in your calculations) Examples: 12340 or 5670 (include the zero in the units column, Canvas will add a comma for you)
Radioactive decays always follow first order. Calculate the rate constant (in s-1 unit) of decay of 24Na (t1/2 = 19.9 h). Use scientific notation.
