A sample has a C614 activity of 0.0089 Bq per gram of carbon. (a) Find the age of the sample, assuming that the activity per gram of carbon in a living organism has been constant at a value of 0.23 Bq. (b) Evidence suggests that the value of 0.23 Bq might have been as much as 44% larger. Repeat part (a), taking into account this 44% increase.

A sample has a Subscript 6 Superscript 14 Baseline Upper C activity of 0.0060 Bq per gram of carbon. (a) Find the age of the sample, assuming that the activity per gram of carbon in a living organism has been constant at a value of 0.23 Bq. (b) Evidence suggests that the value of 0.23 Bq might have been as much as 23% larger. Repeat part (a), taking into account this 23% increase.
Living matter has a carbon-14 activity of about 24.0 counts/min per gram of carbon. What is the age of an artifact for which the carbon-14 activity is 3.00 counts/min per gram of carbon?

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
In a living organism, the decay of C-14 produces 15.3 disintegrations per minute per gram of carbon. The half-life of C-14 is 5730 years. A bone sample with 2.6 g of carbon has 15.7 disintegrations per minute. How old is the bone sample in years?
A skeleton has a carbon-14 decay rate of 0.27 disintegrations per minute per gram of carbon. When did the animal live? Assume that living organisms have a carbon-14 decay rate of 15.3 d/min g C and that carbon-14 has a half-life of 5730 yrs.
A sample of radioactive material contains 1.1E15 atoms and has an activity of 6.3E11 Bq. What is its half-life? A sample of radioactive material contains 1.1 x 1015 atoms and has an activity of 6.3 x 1011 Bq. What is its half-life? 1.16E3 X Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to...
