Q3) What is the half-life of a 100.0 g sample of nitrogen-16 that decays to 12.5 g of nitrogen-16 in 21.6 s?
Added by Troy P.
Step 1
Half-life is the time it takes for half of the radioactive isotopes in a sample to decay. In this case, we start with 100.0 g of nitrogen-16 and end with 12.5 g. This means that the sample has gone through three half-lives. Why three? Because 100.0 g reduces Show more…
