It is always very frustrating to me when I find reference values of different hormones expressed in "mols."  Thanks to Laura K., I now know the relationship between "mols" and "grams" of 17-OHP (ng/dl=nmol/L x 35, right Laura K. ?)  But since, as Joan W. once pointed out, a "mol" is related to the atomic weight of an element and, therefore, different for every substance, I am at a loss to know how to convert to "grams" for anything else---testosterone, androstenedione, LH, FSH, etc.

Does anyone know of a website that would help with translating from "mols" to "grams" for some of the most common hormones? Or which reference book I would use to look up this information?  Once I have a basic starting point, it should not be a problem juggling between different factors of 10.  Any leads would be greatly appreciated.  Thanks!
