A 10.00 g sample of wood from an archaeological site
produced 3072 β particles in a 10-hour measurement owing to the
presence of carbon-14, while a 10.00 g sample of new wood produced
9216 β particles in the same period of time. The half-life of
carbon-14 is 5730 years. How old is the wood from the
archaeological site?

A 2.10-g sample of wood from an archaeological site gave 8600 disintegrations of 14C in a 10-hour measurement. In the same time, a 2.10-g modern sample gave 19000 disintegrations. Calculate the age of the wood. The half-life of carbon-14 is 5730 years.
Carbon-14 has a half-life of about 5730 years. If a sample from an archaeological site has only 12.5% of the normal C-14 abundance, it must be ___ years old.
A 75 g sample of charcoal (assume only carbon) from an archaeological excavation is found to have an activity of 6 Bq from the decay of carbon-14. Use the following information to carbon-date the site. Activity of 1 g of fresh carbon = 0.25 Bq. half-life of carbon-14 = 5730 years.
In a C-14 dating measurement, a 1.00 g wood sample from a cave fielded 7900 counts over a 20hr period, while a 1.00g sample from a reasonably similar tree outside the cave fielded 18,4000 counts over the same period. How old is the sample from the cave given that the half life of C-14 is 5.73*10^3yr?
The age of a piece of wood from an archeological site is to be determined using the Carbon-14 method. The activity of the sample is measured to be 0.671 times the Carbon-14 activity of living plants. What is the age of the sample in years? (The half-life of the Carbon-14 isotope is 5730 years.) Submit Answer Tries 0/20
1A)The age of a piece of wood from an archeological site is to be determined using the Carbon-14 method. The activity of the sample is measured to be 0.741 times the Carbon-14 activity of living plants. What is the age of the sample in years? (The half-life of the Carbon-14 isotope is 5730 years.) B)A newly discovered particle, the SPARTYON, has a mass 945 times that of an electron. If a SPARTYON at rest absorbs an anti-SPARTYON, what is the...
A piece of charcoal (essentially 100% carbon) from an archaeological site in Egypt is subjected to radiocarbon dating. The sample has a mass of 3.82 g and a 14C activity of 0.64 Bq. The initial activity is 0.25 Bq per gram of carbon. Calculate the age of the charcoal sample. ^please help me to calculate the half life please help me to calculate the half life
Problem # 8 Discuss Radioactive Decay. Outline the Principles of Carbon Dating. Provide necessary Mathematical Equations. Total 250 Words Minimum. Solve the following 4 problems. Show Full Work. Problem # A: A chemist determines that a sample of petrified wood has a carbon-14 decay rate of 6.00 counts per minute per gram. What is the age of the piece of wood in years? The decay rate of carbon-14 in fresh wood today is 13.6 counts per minute per gram, and...
A wooden object from the site of an ancient temple has a carbon-14 activity of 10 counts/min compared with a reference piece of wood cut today that has an activity of 40 counts/min. If the half-life for carbon-14 is 5730 y, what is the age of the ancient wood object? Please Express your answer to two significant figures and include the appropriate units.
Modeling Exponential Growth and Decay Madeleine Younes A wooden artifact from an archaeological dig contains 76 percent of the carbon-14 that is present in living trees. To the nearest year, about how many years old is the artifact? (HINT: The half-life of carbon-14 is 5730 years.) The artifact is approximately years old.
