If the above leaf fossils contain 24 ppm 14C and 640 ppm of 14N, determine the age of the fossils.
Here the number of half-lives needed is not an integer number, but is a fractional number. In this situation you must use a mathematical expression, or a graph, to find the solution. The mathematical expression is as follows:
Age in half-lives = 3.322 X log10[(p+d)/p]. Apply this mathematical expression to determine the age.
