5. Gold-191 has a half-life of 12.4 hours. What mass of this isotope would remain after 49.6 hours if you started
with a 7.50 mg?
6. The half-life of cesium-137 is 30.2 years. If the initial mass of a sample of cesium-137 is 1.00 kg, how much
will remain after 151 years?
7. Given that the half-life of carbon-14 is 5730 years, consider a sample of fossilized wood that, when alive,
