How to solve radioactive dating problems
Half of what remains decay in the next half-life, and half of those in the next, and so on.This is an exponential decay, as seen in the graph of the number of nuclei present as a function of time.
Here, we postulate that the decrease in is solely due to nuclear decay.

Radioactive carbon has the same chemistry as stable carbon, and so it mixes into the ecosphere, where it is consumed and becomes part of every living organism.
Carbon-14 has an abundance of 1.3 parts per trillion of normal carbon.

Thus, if you know the number of carbon nuclei in an object (perhaps determined by mass and Avogadro’s number), you multiply that number by to find the number of nuclei in the object.
