Radioactive decay can be described by the following equation In A = In Ao – kt
where Ao is the original amount of the substance, A is the amount of the substance remaining after timet,
and k is a constant that is characteristic of the substance.
For the radioactive isotope chromium-56, k is 1.17 x 10-2 minutes
If the original amount of chromium-56 in a sample is 38.8 mg, how much chromium-56 remains after 6.20
minutes have passed?
mg
