11. At death, a nobleman in ancient Egypt was mummified and his body contained 1.4 x 10 3 g of potassium-40 (t1/2 = 1.25 x 10° yr), 1.2 x 108 g of carbon-14 (t1/2 = 5730 yr) and 4.8 x 10 14 g of tritium (hydrogen-3) (t1/2 = 12.26 yr). Calculate the mummy's age with all three elements and then identify which element gave the most accurate estimate of the mummy's age. 100% Give Feedback to Micro
