If an ancient sample of charcoal has an abundance fraction of 14C = 1/20 the atmospheric abundance, how old is it? a. 25000 years. b. 19000 years. c. 48000 years. d. 38000 years.
Homework Answers
he formula for the age in years of a sample, given the percent of natural c14 remaining is:
now , remaining carbon in percentage= 1/20 = 5%
so , putting in formula we get, age= 24634 yrs = 25000 yrs approx

Carbon 14 (14c) dating assumes that the carbon dioxide on Earth today has the same radioactive content as it did centuries ago. If this is true, the amount of 14c absorbed by a tree that grew several centuries ago should be the same as the amount of 14c absorbed by a tree growing today. A piece of ancient charcoal contains only 20% as much radioactive carbon as a piece of modern charcoal. How long ago was the tree burned to...

Radiocarbon or 14C is a widely used tracer for groundwater movement for up to 30,000 years. 14C can be used to estimate recharge rates and horizontal flow rates important for water related policy decisions. 14C has a half-life of 5730 years and the ratio of 14C to all C from biological material is 1.3 × 10−12. The atomic mass of carbon is 12.0107 g/mol. Your sample is 0.29 g of carbon. The activity of this sample, due to presence of...

When the organism dies, the proportion of 14C decreases as a result of radioactive decay, and the age of the organism can be determined if the proportion of carbon-14 in its remains is measured. If the proportion of 14C in an...
