An archaeologist finds some ancient jewelry made from bone. The jewelry has a carbon mass of 482 g (HINT: Assume all the carbon is 12C and determine the number of atoms, 12C has a molar mass of 12 g/mol) 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). The ratio of 14C to 12C when the animal died was 1.25x10-12 & the half-life of 14C is 5730 y. Additionally, 1 mol = 6.022x1023 particles, 1 y = 365.25 days, & 1 day = 24 h. age of bone =
