This problem is related to the activity of 14 C in a living organism and radioactive dating for a dead organism. The half-life of 1.4 C is 5,730 years and assume that in a living organism there is one atom of 1.4 C for every 8.3x 1011 atoms of b?C. Given: the molar mass of b? C is 12 gram/mol and there are 6.02 x 1023 atoms in one mole of a substance. Determine the number of 14 Catoms present...

11. My Notes Ask Your Teacher -/10 points Content Carbon dating An archaeologist finds some ancient jewelry made from bone. The jewelry has a carbon mass of 435 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 11 decays/s. Determine the age of the bone (and presumably the jewelry). Remember, the ratio of 14C to 12C when the animal died was...
