An archaeologist finds some ancient jewelry made from bone. The jewelry has a carbon mass of 392 g (HINT: Assume all the carbon is ¹2C and determine the numb atoms, 12C has a molar mass of 12 g/mol) and careful measurements show that the remaining 14C has a current decay rate of 26 decays/s. Determine the age of the 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 = 6.022x 1023 particles, 1 y= days, & 1 day = 24 h. age of bone
