An ancient wooden club is found that contains 78 g of carbon and has an activity of 7.3 decays per second. Determine its age assuming that in living trees the ratio of 14C/12C atoms is about 1.3×10^(-12).
Added by Ana L.
Step 1
3 x 10^(-12) Weight of carbon = 78 g N0 = (1.3 x 10^(-12)) x 0.078 / (12 x 10^(-27)) N0 = 0.0611 x 10^15 N0 = 6.11 x 10^13 Show more…

(II) An ancient wooden club is found that contains $85 \mathrm{~g}$ of carbon and has an activity of 7.0 decays per second. Determine its age assuming that in living trees the ratio of ${ }^{14} \mathrm{C} /{ }^{12} \mathrm{C}$ atoms is about $1.3 \times 10^{-12}$.
A wooden artifact has a $^{14} \mathrm{C}$ activity of 18.9 disintegrations per minute, compared to 27.5 disintegrations per minute for live wood. Given that the half-life of $^{14} \mathrm{C}$ is 5715 years, determine the age of the artifact.
