Nitrogen-13 emits beta radiation and decays to C-13 with a half-life of 10 min. Assume a starting mass of 2.0 grams. How many grams of that isotope will remain after 40 min?
Added by James C.
Step 1
Given that the half-life of Nitrogen-13 is 10 minutes and the total time elapsed is 40 minutes, we can calculate the number of half-lives as: \[ N = \frac{40 \text{ minutes}}{10 \text{ minutes}} = 4 \] Show more…

Nitrogen-13 $\left(^{13}_{7} \mathbf{N}\right)$ is a radionuclide that decays by positron emission $(^{0}_{+1} \mathrm{e})$to carbon-13 $\left(_{6}^{13} C\right)$ with a half-life very close to 10 minutes. If we begin with a sample containing 100 micrograms of nitrogen-13, how much N-13 will remain after a period of two half-lives?

Radioactive nitrogen-13 has a half-life of 10. minutes. Calculate the mass of this isotope that remains after an hour in a sample that originally contained $96 \mathrm{mg}$.
