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

Calculate the mass in grams of 1 mole of neutrons given the following conversion factors: 1 n° = 1.008665 amu, 1 amu = 1.660538 x 10-24 g, and 1 mole = 6.02214 x 1023 things Use units to set up this problem. (answer = 1.00866 g/mol)
Show how to calculate the mass of a proton, neutron, and electron in kilograms using the the Table 1 and the equality statement: 1 amu = 1.66054 x 10-27 kg
The planet Zoltan is located in a solar system in the Andromeda galaxy. On Zoltan, the standard unit for the amount of substance is the wog and the standard unit for mass is the wibble. The Zoltanians, like us, chose carbon-12 to define their standard unit for the amount of substance. By definition, one wog of C-12 atoms contains 2.50 x 1021 atoms. It has a mass of exactly 12 wibbles. What is the mass, in wibbles, of 1 wog of nitrogen atoms? What is the mass, in wibbles, of 5.00 x 10-1 wogs of O2? What is the mass, in grams of 1 wog of hydrogen atoms? Expert Solution
