🤓 Based on our data, we think this question is relevant for Professor Fadeeva's class at RUTGERS.
We’re being asked to determine how many U-238 atoms will a sample of U-238 contain today if it initially contained 1.6 x 1018 atoms when the universe formed 13.8 billion years ago.
The half-life of U-238 is 4.5 billion years.
The half-life for the radioactive decay of U-238 is 4.5 billion years and is independent of initial concentration.
If a sample of U-238 initially contained 1.6×1018 atoms when the universe was formed 13.8 billion years ago, how many U-238 atoms will it contain today?
