Calculating Mass and Decay: Example Questions
Not what you're looking for?
Part 1:
(7-atomic mass)Be decays with a half-life of about (53-atmic mass) d. It is produced in the upper atmosphere, and filters down onto the Earth's surface. If a plant leaf is detected to have 374 decays/s of (7-atomic mass)Be, how many days do we have to wait for the decay rate to drop to 14.2/s?
Part 2:
Calculate the initial mass of 7-Be on the leaf.
