Some fossil bones containing 1/32 of their original amount of carbon-14 are found. How many half-lives have passed? How old are the bones? (HINT: The half-life of carbon-14 is 5,730 years. If 1/8 of the original amount of carbon-14 was present, 1/8 = 1/23 or 1/(2x2x2), therefore 3 half-lives would have passed and therefore, the bones would be 5,730 years x 3 = 17,190 years old)

1. An archaeologist conducting a dig in New Mexico discovers some ancient bones. radiocarbon analysis indicates that 0.249 of the original amount of carbon-14 is left a. approximately how many half-lives have elapsed/passed b.if the single half-life value for carbon-14 is 5730 years, approximately how old are the remains?

1. The half-life of carbon-14 is 5730 years. A sample is found to have one-eighth the original amount of carbon-14 in it. How old is the sample? 5730 years, 716 years, 45800 years, 17200 years 2. Why wouldn't you use carbon-14 dating on a piece of shell that was estimated to be 1 million years old? Sea shells do not have radioisotopes, carbon dating is only useful on plants, uranium dating is better for items older than 1/2 million years,...

Carbon-14 is a radioactive isotope of carbon with a nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating. The half-life of carbon-14 is 5,730 years. If a fossilised tree trunk originally contained 8 nanograms of C-14, how long will it take for the C-14 to decay to 1 nanogram

Phosphorus-32 has a half-life of 14.0 days. Starting with 8.00 g of 32P, how many grams will remain after 70.0 days ? Carbon-14 has a half-life of 5730 years. In a plant fossil, you find that the 14C has decayed to 1/32.0 of the original amount. How long ago was this plant alive?

Question 4: Carbon dating (3 points) Archaeologists use the exponential, radioactive decay of carbon-14 to estimate the death dates of organic material. The stable form of carbon is carbon-12, and the radioactive isotope carbon-14 decays over time into nitrogen-14 and other particles. Carbon is naturally in all living organisms, and the carbon-14 that forms in the upper atmosphere enters into living things as long as they are taking in material (food, air, etc.) that contains carbon. We...

Carbon-14 is a radioisotope that is used for dating biological organisms. The half-life of C-14 is 5730 years. When a one-gram sample of carbon from fresh peat is measured for radioactivity, 900 beta decays are recorded every hour. A one-gram sample of carbon is obtained from a peat deposit and is measured for radioactivity. If 113 beta decays are observed every hour, how many half-lives of C-14 have passed since the deposit was formed? A. 1/8 B.3 C.113 D.8 Approximately...

A sample of charred animal bones found in a cave has a carbon-14 decay rate of 5.2 disintegrations per minute per gram of carbon (5.2 dis/min-g C). Living organisms have a decay rate of 15.3 dis/min-g C. The half-life of carbon-14 is 5715 yr. How old is the bone sample? (All radioactive elements decay according to first order kinetics.) a)2.8 x 10 3 yrs b)3.9 x 10 3 yrs c)1.9 x 10 3 yrs d)8.9 x 10 3 yrs

Need help with these problems. 1. A doctor prescribes 150 milligrams of a therapeutic drug that decays by about 10% each hour. Write an exponential model representing the amount A in milligrams of the drug remaining in the patient's system after t hours. 2. Suppose a sample of a radioactive substance weighs 38 mg. One year later, the sample weighs 23.5mg. What is the half-life of this substance? 3. Carbon-14 has a half-life of 5,730 years. A fossil is found...
