Oxygen has an atomic number of 12. However, the isotope oxygen-14 has a half-life of 70.62 seconds. What would happen to 1 g of oxygen-14 after 70.62 seconds? a) Half of the atoms of oxygen-14 will decay b) All oxygen-14 atoms will decay c) 70.62 atoms of oxygen-14 will decay in half the time d) We cannot estimate how many atoms will decay

The half-life for the radioactive decay of C-14 is 5730 years. Part A: How long will it take for 20% of the C-14 atoms in a sample of C-14 to decay? Part B: If a sample of C-14 initially contains 1.4 mmol of C-14, how many millimoles will be left after 2260 years?

The half-life of ${ }^{131} \mathrm{I}$ is $8.04$ days. (a) Convert the halflife to seconds. (b) Calculate the decay constant for this isotope. (c) Convert $0.500 \mu \mathrm{Ci}$ to the SI unit the becquerel. (d) Find the number of ${ }^{131}$ I nuclei necessary to produce a sample with an activity of $0.500 \mu \mathrm{Ci}$. (e) Suppose the activity of a certain ${ }^{131}$ I sample is $6.40 \mathrm{mCi}$ at a given time. Find the number of half-lives the sample goes through in $40.2 \mathrm{~d}$ and the activity at the end of that period.
