This is a basic math puzzle requiring familiarity with
chemistry. The cache is not at the stated coordinates. To get the
fractional portion ( N39°35.z ) you will have to figure out the
numbers by way of the math problem below. The key for the
encryption of the coordinates (k) begins with the following
molecular formula: C14H9Cl5
Divide the following number, 57702 by the non-decimal portion of
the molecular weight(g/mol) of this stuff (k) to find the
fractional portion of the Latitude(z)
Next, to find the fractional portion of the Longitude, divide
26.904 by the non-decimal portion of K's molecular mass.
