The isotope Bi-214 decays from 60.00 g to 7.50 g in 1 hour.  What is the amount of time for one half-life?

What percent of the original sample remains after 4 hours?

Radioactive C-14 has a half-life of about 5,000 years.  If a fossil is only about 25% as radioactive (compared to the original) as expected for living tissue of the same mass, the age of the fossil is about:
