An archaeologist finds some ancient jewelry made from bone. The jewelry has a carbon mass of 303 g (HINT: Assume all the carbon is 12C and determine the number of atoms) and careful measurements show that the remaining 14C has a current decay rate of 14 decays/s. Determine the age of the bone (and presumably the jewelry). Remember, the ratio of 14C to 12C when the animal died was 1.3×10-12 & the half-life of 14C is 5730 y. age of...
