There are two radioactive elements, elements A and B. Element A decays into element B with a decay constant of 2/yr, and element B decays into the nonradioactive isotope of element C with a decay constant of 1/yr. An initial mass of 3 kg of element A is put into a nonradioactive container, with no other source of elements A, B, and C. How much of each of the three elements is in the container after t yr?

I only need help with part c). Thanks!
As a radioactive specimen decays, its activity decreases exponentially as the number of radioactive atoms diminishes. Some radioactive species have mean lives in the millions (or even billions) of years, so their exponential decay is not readily apparent. On the other hand, many species have mean lives of minutes or hours, for their exponential decay is easily observed. According to the exponential decay law, the number of radioactive atoms that remain after...
