The specific radiocarbon activity of a sample of wood is 6.25 gms dpm/gm of carbon. The specific activity of NBS oxalic acid standard is 14.27 dpm/g of carbon. What is the age of the wood sample?
An ancient club is found that contains 140 g of pure carbon and has an activity of 5.5 decays per second. Determine its age assuming that in living trees the ratio of (14c 12c) atoms is about . Note that the half life of carbon-14 is 5700 years and the Avogadro number is 6.02x10^23. in years
An ancient wooden club is found that contains 79 g of carbon and has an activity of 7.0 decays per second. Determine its age assuming that in living trees the ratio of 14C/12C atoms is about 1.3×10−12.
An ancient wooden club is found that contains 65 g of carbon and has an activity of 8.1 decays per second. Determine its age assuming that in living trees the ratio of 14C/12C atoms is about 1.3×10^-12. Answer In years
Watch It! #2 NNA Where is nitrogen found in abundance as N_? What percentage does it make up? Watch It! #4 Explain how nitrogen can get back into the atmosphere. How is the process of "fixing" nitrogen from the atmosphere different from the way carbon is fixed in the carbon cycle?
An ancient club is found that contains 190 g of pure carbon and has an activity of 6.5 decays per second. Determine its age assuming that in living trees the ratio of (14C / 12C) atoms is about 1.20×10-12. Note that the half life of carbon-14 is 5700 years and the Avogadro number is 6.02×1023. Answer in years.
An ancient wooden club is found that contains 66 g of carbon and has an activity of 7.5 decays per second. Determine its age assuming that in living trees the ratio of 14C/12C atoms is about 1.3×10−12. Please show your work.
An ancient wooden club is found that contains 87 g of carbon and has an activity of 7.0 decays per second. Determine its age assuming that in living trees the ratio of 14C/12C atoms is about 1.3×10−12 csn you please explain every step, thank you
