Radioactive decay can be described by the following equation In A = In Ag- kt where Ag is the original amount of the substance, A is the amount of the substance remaining after time t, and k is a constant that is characteristic of the substance. For the radioactive isotope chromium-51, k is 2.50 x 10-2 -1 days If the original amount of chromium-51 in a sample is 29.2 mg, how much chromium-51 remains after 30.5 days have passed? mg
