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.
A certain drug has a half-life in the body of 7.5 h. What should the interval between doses be, if the concentration of drug in the body should not fall below 25.% of its initial concentration? Round your answer to 2 significant digits.
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 = 6.022x1023 365.25 days, & 1 day = 24 h. particles, 1 y = age of bone =
