Question: Consider the decay series A B C D where A, B, and C are radioactive isotopes with half-lives of 4.50 s, 15.0

Consider the decay series
A → B → C → D
where A, B, and C are radioactive isotopes with half-lives of 4.50 s, 15.0 days, and 1.00 s, respectively, and D is nonradioactive. Starting with 1.00 mole of A, and none of B, C, or D, calculate the number of moles of A, B, C, and D left after 30 days.
