An archaeologist finds some ancient jewelry made from bone. The jewelry has a carbon mass of 484 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 11 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 = 6.022×1023 particles, 1 y = 365.25 days, & 1 day = 24 h. age of bone =

A certain drug has a half-life in the body of 5.5 h. What should the interval between doses be, if the concentration of drug in the body should not fall below 35.% of its initial concentration? Round your answer to 2 significant digits.
Iodine-131 (half-life = 8.02 days) tracer with 214 counts per minute was added to water as iodide ion to measure plant growth. After 30.0 days the counts per minute was measured to be 15.7 counts per minute. How much I-131 tracer did the plant absorb?
In a living organism, the decay of C-14 produces 15.3 disintegrations per minute per gram of carbon. The half-life of C- 14 is 5730 years. A 2.7 g sample of bone has 39.2 disintegrations per minute. How old is the bone sample in years? Answer:
Oxygen-22 disintegrates into Fluorine with a decay rate of λ = 0.315 per seconds. Considering an initial amount of Oxygen 22, which percentage of it will be left after 5.8 seconds? Keep three significant digits.
Radioactive decay can be described by the following equation In A = In Ao – kt where Ao is the original amount of the substance, A is the amount of the substance remaining after time t, and k is a constant that is characteristic of the substance. For the radioactive isotope phosphorus-32, k is 4.85 × 10-² days. If the original amount of phosphorus-32 in a sample is 55.4 mg, how much phosphorus-32 remains after 16.3 days have passed?
Hi, I need help with this step-by-step, please. Thank you. Even more interesting is how the researchers determined the age of the sharks. Normally, youcould look at the decay of carbon-14 in the bone of an animal to determine its age. By comparingthe current amount of carbon-14 in the bone to the amount of carbon-14 that was in the boneinitially, you can determine how much time has passed (the age of the animal). This doesn’twork with Greenland sharks, though! Greenland sharks don’t have bones. They just havecartilage. Researchers determined, however, that the carbon-14 in certain proteins in the eye lensof the sharks could be dated because those proteins are set from the time that the shark is bornand are never replaced (most proteins in living organisms are constantly being broken down andreplaced, but not these proteins in the eye lens of the Greenland shark!).[Here’s the problem to solve and the information you need to solve it.] Let’s assume thatresearchers find a new Greenland…
