[youtube NgAsbA98cww] Click on the questions below to watch explanations videos: Basic Questions (Solving for Quantity) The half-life of a foul smelling substance is 4 years.

- The first step is to determine the number of half lives that have elapsed. number of half lives = 1 half life/6.13 hours x 1 day x 24 hours/day. number of half lives = 3.9 half lives. For each half life, the total amount of the isotope is reduced by half.
- The half life of a substance or a decaying material (or population) is the amount of time it takes for 50% of the original amount of substance (or material or population) to decay. If we use the symbol to denote the half life of a process, and to represent the amount of a substance initially present then
- 12.32 years Your equation is the one for compound interest rate on a principle amount. The math is similar (exponential function) but not the same arrangement. That is a good approach for this problem when given an annual rate. The definition of a “half-life” is the time that it takes for 1/2 of the compound to decay. SO, we just need to
- And then for a particular element with a particular half-life you can just solve for the k, and then apply it to your problem. So let's do that in this video, just so that all of these variables can become a little bit more concrete. So let's figure out the general formula for carbon. Carbon-14, that's the one that we addressed in the half-life. We saw that carbon-14 has a half-life …
